| 摘 要： | 降水预压是通过降低地下水位而加固软土地基的一种软基处理技术。这项处理技术的中孔压变化与堆载预压的孔压变化有所不同, 它是在通过降水减小静水压力增大有效正应力, 从而使土体固结沉降。通过上海浦东某工程降水预压试验的孔压测试, 本文分析了降水预压加固软土地基原理及孔隙水压力效应。

| Abstract: | Dewatering is a new technology in soft soil foundation treatment. By dewatering, hydrostatic pressure decreases and effective normal stress correspondingly increases. Then the soft soil is consolidated and subded . In this paper, by analyzing pore-water pressure monitoring data of the dewatering and preloading test on a project in Pudong , the mechanism and pore water effect of dewatering foundation reinforcement are briefly discussed. |

| Keywords: | Detwering reinforcement Pore water pressure effect Monitoring |
