摘要
山西省淜头水电站工程拦河闸基础处理工程采用高压旋喷桩对地基加固,进行多次现场生产型试验研究粉质黏土层中的成桩桩径问题,最终确定了合适的旋喷参数和施工工艺,提高了黏土土层的地基承载力,缩短了工期,节约了投资,为其他同类工程的解决提供了成功范例。
High pressure jet grouting piles were adopted in sluice foundation treatment work of Shanxi Pingtou Hydropower Station Project for foundation reinforcement. Several on-site production tests were conducted for studying the pile diameter problems in silty clay layer, appropriate spin spray parameters and construction techniques are finally determined to improve foundation bearing capacity of the clay soil layer, shorten the construction period, and save investment, thereby providing successful example for solving other similar projects.
