摘要
预制桩沉桩引起的挤土效应和桩基施工完成后的质量问题在软土地基中时有发生,结合两个软土地基预制桩基的工程实例,对软土地基中沉桩挤土机理及对桩周土体和环境的影响进行了探讨。针对实例中的具体质量问题产生的原因进行详细分析,并提出了合理的处理方法。总结了软土地基中降低挤土效应的常用措施,可供软土地基中类似工程的设计和施工提供参考与借鉴。
The precast pile caused by squeezing soil effect and complete quality problems after the construction of pile foundation in soft soil foundation have occurred,combined two soft soil foundation precast pile foundation engineering example,soft soil foundation pile driving mechanism,the influence on the surrounding soil and the environment were discussed. The reasons according to the quality problems were analyzed in detail,and the reasonable processing method was put forward. The common measures to reduce soil squeezing effect in soft soil foundation were summarized,which can be used as reference for design and construction of similar projects in soft soil foundation.
