| Abstract: | By means of stability analysis for slurry trench of diaphragm wall consideringsoil arch action,the corrective limit condition and the transformed limit equilibrium equationwhich physical conception is clear for slump mass is presented,and the clear formula for thecritical dip angle of slump mass' bottom in the most dangerous state and for thecorresponding slurry critical specific gravity in the limit equilibrium state are deducted. Someoffection and fluctuation of results which are caused by some factors are also obtained byinferences and analysis to the formula. |
