Abstract:
The datum of seepage accidents of 372 diaphragm walls in 11 subway stations on the diaphragm walls had been investigated and analyzed by statistical method. the influences factors that the seepage accidents occurred on diaphragm walls had been analyzed systematically: engineering geology and hydrogeology condition, construction quality effect of supporting wall, complicated environment factors at construction field, and so on. The principle including of primary persuasion, combination of the persuasion, plugging and reinforcement must be abided when facing the seepage accidents, therefore, the different preventing and handling measures had been given according to different seepage condition, such as slip casting behind the diaphragm wall, reducing the hydraulic pressure of confined water through the dewatering well, reducing the environment load influence on the excavation, improving the construction technology and promoting the quality.
