谈软弱黏性土地区采用静压桩试桩的重要性

Importance of Test Piles Using Static Pressure Piles in Soft Clay Soil

近年来,随着国内经济的迅猛发展,越来越多建(构)筑物向空间及地下延伸,由此为基础工程带来严峻的考验。桩基础是目前改善地质条件,提高地基承载力的有效途径。在一些存在软弱黏性土的地区,普遍以摩擦桩为主。论文介绍了当存在软弱土层时,静压摩擦桩终压力达不到单桩竖向承载力,工程建设前进行试桩的重要性。

In recent years, with the rapid development of domestic economy, more and more construction（construction） has been built into space and underground extension, which has brought severe test to the basic project. The pile foundation is the effective way to improve geological conditions and improve the bearing capacity of foundation. In some areas of soft clay, friction piles are commonly used. In this paper, when there are soft soil layers, ultimate pressure of static pressure is less than single vertical bearing capacity, and the importance of test pile before construction is carried out.
