浅埋地下结构外水压折减系数试验研究

TESTING STUDY OF REDUCEMENT FACTOR FOR THE PORE WATER PRESSURE OF UNDERGROUND STRUCTURE

通过模型试验，探讨地下结构外水压力是否可以折减，试验介质采用中砂和粘土。试验结果说明：对浅埋地下结构，如不采取导排水措施，外水压力是不能折减的。

A testing study is made to check if the pore water pressure of underground structure can be reduced or not. The test media are sand and clay. The test result shows that the pore water pressure of underground structure can not be reduced if the drainage works are not made.
