# Rock Tunnel #

T o p i c s	I d e a s
Development of Integrated System for Tunnel Support Design Check	Current tunnel support design methods rely too much on empical approach A cased-base reasoning approach must adopted to examine the design adequacy Design check by numerical tools are also required
Development of Expert System for Tunnel Construction	Tunnel behaviours can not be fully foreseen in design stage Decision making on site depends too much on experienced person Lack of suitable tunnel safety criterion on site Feedback of construction data on design not actually conducted An expert system for solving rock support interaction problem on site is necessary
Tunnel Construction Data Management	Data related to tunnel constuction were not saved Data collection and eletronic database managing system by computer should be constructed to replace the artificial manner Instant responce can be concluded with high efficient database managing system Tunnel database will be sustainable
Prediction of Geologic Weakness Using Seismic Method	Locating geologic weakness, including watering bearing zone, fault zone etc, ahead of tunnel excavation face The Horizontal Seismic Prospecting (HSP) technology using the reflection seismic method is validated This study will try to Extending the HSP method into a 3D HSP method Validation in real tunnel during its construction

# Weak Foundation #

T o p i c s	I d e a s
Seismic Analysis of Earth structures and Deep Foundations	Considering the seismic effect has been a subject in the design of Earth structures and Deep Foundations Traditional methods such as psudo-static approach, equilivalent elastic approach, or parameter reduction approach are no more sufficient in design calculation A new numerical tool is aimed which can solve foundation problems considering seismic effect and optimum constitution law for soils
Interaction of Shield Tunneling with Existing Building Structures	Current design of Shield Tunneling did not take into account the interaction with Existing Building Structures In weak ground, maintain the stability of neiboring structures is important and adequate design model and analysis is necessary New design approach using numerical tools such as FLAC, FLUSH can construct a standarized design routine both for static and dynamic situation

# Earth Dam Stability #

T o p i c s	I d e a s
Study of concrete face rockfill dams (CFRD)	CFRD has advantages such as high safety, low cost, short construction time CFRD can be very competitive in Taiwan The anti-leekage diaphram structure is the critical portion for CFRD, numerical analysis can be adopted to study its behaviour when the dam is deformed
Study of Design Problems for Earth Dams	Burrow site of earth dam is difficult to get, in-situ materials has to be used Use a asphalt concrete core wall can be a good alternative To improve the quality of earth dam monitoring, an automatic system should be applied
