Abstract

Abstract

The stability for the trench of diaphragm walls is related to the safety and quality of trenching construction. To ensure the stability of trenches, the stress variation in the earth of trench walls was analyzed under trenching construction, the stability conditions and influencing factors of trench walls were discussed, the influence of space-time effect was discussed emphatically, and the influence of space-time effect was verified by the measured data. The results showed that: the time effect had a significant effect on the stability of the trench. Increasing the mass density of slurry and the level of mud and could improve the trench stability, and the latter was more effective. The shallow soil in the middle of the trench was more disturbed during construction of trenching, and the lateral displacement, the subsidence of the earths surface and the earth pressure appeared a certain spatial effect.
