高压旋喷桩在工程地基处理中的应用

Application of High-Pressure Chemical Churning Pile in the Engineering Ground Treatment

本文通过某大厦采用旋喷桩复合地基的工程实例,就高压旋喷桩在高层建筑地基处理中的应用做简单阐述,主要针对目前工程桩可选桩型较少,特别是有些工程地质情况较复杂,如持力层埋置较深,场地孤石大且多,地基承载力要求又高的工程(高层建筑),选用常用桩型(冲孔桩或人工挖孔桩)不但施工周期长,而且又不经济等问题,提出一种切实可行的地基处理方法-高压旋喷桩,以供大家借鉴。

According to the engineering example which adopted chemical churning pile composite foundation.The thesis briefly expatiate on theapplication of high-pressure chemical churning pile in the high-rise building ground treatment.Mainly aimed aimed at the lack of optionalengineering pile presently,especially some complex geological-condition engineerings.Such as bearing stratum deeply inearthed,more large isolatedstone in the field,strict request of the subgrade bearing capacity.The questions of the usual engineering pile were not only need long constructionperiod,but also not economy.So put forward a method of pressing and feasible ground treatment-High-Pressure Chemical Churning Pile. And can beused for reference.
