发布时间:2019-02-22 11:59
【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。
[Abstract]:The compaction effect caused by prefabricated pile driving and the quality problems after the construction of pile foundation occur from time to time in soft soil foundation. Combined with two engineering examples of precast pile foundation on soft soil foundation, The mechanism of piling and compaction in soft soil foundation and its influence on soil and environment around pile are discussed. The causes of the concrete quality problems in an example are analyzed in detail, and a reasonable treatment method is put forward. The common measures to reduce the compaction effect in soft soil foundation are summarized, which can be used as reference for the design and construction of similar projects in soft soil foundation.
