| 摘 要： | 深层水泥搅拌桩是通过深层搅拌机沿深度将水泥浆固化剂与地基土层强制搅拌成桩以加固地基的方法。适宜于加固淤泥，淤泥质土，粉土，含水量较高且地基承载力标准值不大于１２０ｋＰａ的粘性土等软土堪。深层水泥搅拌桩对加固软弱地基效果显著，可以明显提高地基不载力，减少沉降量，施工无振动，对周围环境无污染，经济效益好。

| Abstract: | To adopt cement -- stirring pile is an effective method for strengthening soft foundation.Under the action of stirring pile machine along the foundation depth, cementitious material is stirredintensively with the foundation soil to form the pile and so to strengthen the foundation. It is proper tostrengthen such foundation soil, as sludge, silt soil, silty sand and clay with high water capacity,normal bearing capacity less than 120 KP. The effect of strengthening soft foundation with deep cement -- stirring pile is very evident, it can increase the bearing capacity of foundation, decrease thesubsidence, and work without vibration, without any environmental pollution. In addition, the economicbenefit of using this method is ggreat. |
