Abstract: The stability of the slurry-supported trench excavations during the construction of a diaphragm wall panel has always been a matter of considerable concern. Some methods of the global stability analysis have been derived from either the force equilibrium analysis or the stress limit state analysis based on various types of slipping surfaces or sliding wedges assumed. In order to discriminate the applicability of these methods, a comparative study of their theoretical bases, parametric sensitivity and practical application effectiveness is carried out. It has been found that the trench stability analysis methods established based on the prismatic and apsidal sliding wedge assumption can estimate reasonably the stability of the trench.

Key words: diaphragm wall, panel trench, global stability, slurry-supported excavation, stability analysis method
