摘要
结合软土地基加固处理施工的实例,以CFG桩加固为研究对象,提出运用电流表控制CFG桩长,并采用后插钢筋笼技术对桩体进入持力层的深度与桩身承载力进行控制。结果测得基底CFG桩顶两年最大累计沉降量仅为18.29mm,并经线性回归分析,证明该项技术实用、可行,可取得较好的经济效果,为今后类似工程的施工积累了宝贵经验。
Combined with reinforcement projec CFG pile length with ampere meter was propos ts of soft soil foundation, the ed, and post inserted steel reinf applied to control the depth of pile in bearing stratum and the b from detection show that the accumulated settlement at the top foundation reaches 18. 29 mm. The technology is proved to b analysis and is economic. idea of co orcement ntrolling cage was earing force of pile body. Results of CFG pile in the bottom of the e practical with linear regression
