本文描述在软粘土中开挖浆槽的稳定机理。首先，提出试验槽开挖过程中测得的各种力学性能。根据测量结果，论述了槽壁稳定机理。槽费向内侧位移时（会大到２０—３０ｍｍ）会使作用于槽壁的侧压力（水与土的合成压力）从原来的静止水平（开挖前）下降至与浆压平衡，从而使槽壁得以稳定。再者，按上论述结果，对不同地基条件下的槽开挖的稳定性进行研究，结果指出，正常固结的软粘土只会产生微小的位移，故用浆槽法制作连续墙是可行的。
This paper describes the stability mechanism of the excavation slurry tank in soft clay. First, various mechanical properties measured during excavation of the test tank were proposed. Based on the measurement results, the stability mechanism of the tank wall is discussed. When the trough fee is displaced to the inside (it can be as large as 20-30mm), the lateral pressure acting on the trough wall (combined pressure of water and soil) can be reduced from the original standstill level (before excavation) to equilibrium with the pulp pressure, so that The wall is stable. Furthermore, according to the results discussed above, the stability of trench excavation under different ground conditions was studied. The results indicate that the normally consolidated soft clay will only produce small displacements, so it is feasible to use the slurry tank method to make a continuous wall. .
