ABOUT SHENYANG
Shenyang, as the capital of Liaoning Province, P. R. China, is the economic, cultural,
transportation and business center of northeastern region of China. The largest industrial city in
northeast China, it has a population of about 7 million. It is also renowned for its industrial status
and affluent history. There are three world cultural heritage including Shenyang Imperial Palace,
Zhaoling Tomb and Fuling Tomb. The most important historic site in the city is Shenyang Imperial
Palace(沈阳故宫), the former residence of the Qing Dynasty founder Nurhachi and his successor
Huangtaiji and the place where Emperor Shun Zhi, founding monarch of the Qing imperial rule had
himself crowned. In 1644, the Qing government moved its capital to Beijing and since then,
Shenyang Imperial Palace and Shengjing (Shenyang) came to be known merely as the "sacred
place where the dragon took on wing". During their lifetime Qing rulers from Emperor Kang Xi to
Emperor Dao Guang had come on eleven occasions to offer sacrifices to their ancestors in
Shenyang.
The second largest imperial palace only next to the former Imperial Palace in Beijing,
Shenyang Imperial Palace is by itself a grand architectural conglomeration of halls, pavilions,
towers and temples with carved beams and painted columns architectural styles of the Mongolian,
Han and Manchu nationalities. The Zhaoling (or Northern Mausoleum 北陵) is the cemetery of
Huangtaiji and his wife Borjigid and the Fuling (or Eastern Mausoleum 东陵) is where Nurhachi and
his wife Yihnaran were buried. Tranquility and solemnity reign over the two burial grounds with the
Tianzhu Mountain at the back and the Hunhe River extending in front of the tombs. Some 100
kilometers southeast of the city is Qianshan Mountain known as a scenic area with temples
pavilions and exquisite sculpture.

Presentation Topic
Probabilistic Approach for the Analysis of Rock Excavation Stability
Gang Chen
The deterministic description of rock excavation stability with a safety factor is frequently
insufficient and, sometimes, misleading.
The applications of the probabilistic analysis to
determine the likelihood of a rock excavation failure have been proposed by many researchers.
The probabilistic analysis will lead to a better understanding of excavation stability and provide
more complete information on the safety and stability of rock excavations.
The difficulty in estimating the failure probability of a underground excavation is the complexity of
mathematics involved. In order to overcome this limitation, the first-order second-moment
approximation of the failure probabilities is utilized.
The technique simplifies the computation
significantly and allows for the analysis of relatively complex stability problems.
A few case studies are presented in the paper to illustrate the principles and applications of the
probabilistic analysis of rock excavation stability, including specific discussion on the removable
probability and failure probability of key blocks as defined in the block theory. The study indicates
that the distributions of parameter values play a significant role in the excavation stability, which
cannot be disclosed by the conventional methods of stability analysis. Greater dispersiveness of
the parameter values will lead to a different probability of failure, although the factor of safety
estimated by conventional methods remains the same if the mean values of the parameters are
unchanged.

Presentation Topic
Numerical analysis of the change in groundwater system with tunnel
excavation in discontinuous rock mass
In this study, a 2D finite-element analysis, using the SEEP/W program, was carried out to
estimate the amount of groundwater flowing into a tunnel, as well as the groundwater tables around
wetland areas during and after tunnel excavation through rock mass. Four sites along the
Wonhyo-tunnel in Cheonseong Mountain (Gyeongnam, Korea) were analysed, where the model
domain of the tunnel included both wetland and fault zones. The anisotropy of the hydraulic
conductivities of the rock mass was calculated using the DFN model, which was then used as an
input parameter into the continuum model. Parametric studies were performed on the influencing
factors to minimize uncertainties in the hydraulic properties. Moreover, the volumetric water content
and hydraulic conductivity functions were applied to the model to reflect the ability of a medium to
store and transport water under both saturated and unsaturated conditions.

Presentation Topic
ROCK JOINT GEOMETRY: SIZE AND SURFACE
New ideas for estimating a joint size distribution and determining the contact areas of a rock joint
suggested by Rock Mechanics and Rock Engineering lab of Seoul National University are
introduced. The former idea adopted a distribution-free estimation technique which does not
require any assumption of the joint size distribution type or even of an upper limit on the joint size
distribution [1]. The latter requires only three-dimensional surface coordinates at the initial stage
before shearing, and a joint surface is modelled as a group of triangular planes of which contact
condition is examined by calculating the relative displacement of both surfaces from their initial
locations.

Presentation Topic
Strength failure and crack coalescence behavior of red sandstone specimens
containing two pre-existing fissures
To understand deeply the fracture mechanism of all kinds of rock engineering, it is very
significant to investigate the fracture coalescence behavior of pre-fissured rock. In this
presentation, we have carried out uniaxial compression experiments to evaluate the influence
of fissure angle on the strength, deformability and fracture coalescence behavior of rectangular
prismatic specimens (80×160×30 mm) of red sandstone containing two unparallel fissures (a
kind of new fissure geometry). Both photographic monitoring and acoustic emission (AE)
techniques were all used throughout the entire period of deformation in order to explore the
fracture coalescence process and mechanism. The macroscopic deformation characteristics of
red sandstone containing two unparallel fissures were systematically evaluated by analyzing
the relationship between the stress-time curve and the fracture coalescence process, AE
events. The cracking process depended on both the fissure angle α2 and the heterogeneity of
red sandstone material. And then, the red sandstone specimen containing two pre-existing
fissures are carried out the numerical simulation by PFC2D. Numerically simulated results for
red sandstone specimen containing two fissures under uniaxial compression show a good
agreement with the experimental results. These experimental and numerical results were
expected to improve the understanding of fracture mechanisms of rock engineering with
intermittent structures.
