缓解深厚软基桥头跳车两种方法的现场试验

Field test of two methods for alleviating bridge-head jumping at deep soft foundation

    摘要
  • 摘要: 分别采用真空联合堆载和低强度混凝土桩复合地基处理深厚软基,成功解决了桥头段软基处理中的桥头跳车问题。介绍了两种软基处理方法的地基承载力、沉降和分层沉降等现场测试成果,并对两种处理方法的加固效果和相关经济指标进行了比较分析。

     

    Abstract: To alleviate the problem of vehicles jumping at bridge approaches,vacuum-surcharge preloading and low strength concrete pile(LSCP) composite foundation are used to improve deep soft soil under the highway in Taizhou,Zhejiang Province.The field test results such as bearing capacity,settlement and deep settlement are presented.The performance and some economic index are compared and analyzed in detail.
