摘要
１９９３年山西省忻州地区滹沱河界河铺引水枢纽改建工程采用水泥粉喷技术建造闸墩基础加固桩、挡水坝基础防渗墙获得良好的工程效果。这是一种通过机械对基础土强行搅动并同时喷射水泥粉，使搅拌土自凝形成地下构筑物的施工方法。实践证明地基水泥粉喷建筑物是水利建设中常见的中、浅深度防渗墙及桩基的良好的工程替代方案。
In 1993,the powder deep mixing method has been used on construction of the lock pier and the water retainning dam of diversion works in Hutuo River,Xinzhou district,Shanxi province to improve their foundation soil and the effect is good.This method is using machines to mix the deep soil,and at the same time jetling cement powder to form the underground structures.The practice proved that the shallow or middle depth underground structure of hydraulic engineering formed by jetting cement power is a good alternative for cut off wall or pile foundtion.
