水泥土搅拌桩复合地基沉降计算方法浅谈

水泥土搅拌桩是用于加固饱和软粘土地基的一种有效方法。它通常用水泥作为固化剂,通过特制的深层搅拌机械在地基深部将软土和固化剂强制搅和,使软土硬结而提高地基强度。此法由于其良好的经济效益和社会效益正得到广泛的应用。但最近有关水泥土搅拌桩工程的事故接二连三发生,说明水泥土搅拌桩复合地基沉降计算的实体深基础法的自身局限性。讨论了关于水泥土搅拌桩沉降计算的几种其他方法的优缺点。建议工作人员应根据实际工程特点合理选用计算方法。

Study on Methods of Settlement Calculation of Cement-Soil Mixing Piles

Cement-soil mixing pile is a very effective method in foundation treatment.It usually uses cement as the consolidating material.By a kind of special deep mixing machine,it makes the cement and soil mixed .So the foundation will be strengthened greatly.This mathod is of very good economic and sociable value and has been used widely.After explaining the limitation of methods of settlement calculation of cement-soil mixing piles--"Code Method" or Deep Massive Foundation Method after considering the present quality problem of cement-soil mixing piles, the authors introduce two other methods of settlement calculation of cement-soil mixing piles,and generalize the advantages and disavantages of every method.The articles suggests the working personnel had better select the reasonable method according to the properties of specific projects.
