摘要(Abstract)：
提出了在新建地基工程中采用预挖孔法改进高压旋喷注浆施工的技术方案；探讨了其适用的地质条件；并推导出有关该工艺施工参数的计算方法；对施工质量及经济效益进行了分析
The authors put forward a method of preliminary pitting in the foundation soil under new building to improve the high pressure rotary grouting techniques.They also discussed what geological conditions the method is suitable to.The calculating formula about constructing parameters was deduced.And by using this method,a foundation engineering project of new building become of high quality and good benefit.
