沉桩挤土效应对工程环境的影响及研究综述

Influence on Engineering Environment under Pile Soil Compaction Effect and Research Review to It

在软土地区,沉桩导致桩周土体的侧向变形和隆起,对周围工程环境产生一定的影响。为此,对沉桩挤土效应方面的研究成果进行了综述,重点讨论了理论研究、室内和现场试验的研究概况,指出了挤土效应研究存在的问题,并提出了几点建议,为进一步研究沉桩挤土效应问题指明了方向。

The soil surrounding the pile will be compacted during pile driving,and lateral and upward displacement will take place,which will affect the surrounding engineering environment in a soft soil area.Therefore,the research results are reviewed here on compaction effect of pile driving,especially on the research situations of theoretical research,laboratory and field tests.At last,the problems existed are pointed out about compaction effect,and several suggestions are made,which would give the clear direction for further study on soil compaction effect of pile driving.
