水泥土组合桩是一种新型的地基处理技术和深基坑支护技术 ,这种技术是在水泥搅拌桩基础上发展出来的 ,即在水泥土搅拌桩程桩内插入刚性芯桩。本文简要介绍了水泥土组合桩的构造、工作机理及计算方法。水泥土组合桩具有造价低、承载力高等优点 ,是适合软土地基加固的一种新桩型 Cement-soil composite piles is a new type of foundation treatment technology and deep foundation pit support technology, which is developed on the basis of cement mixing pile, that is, inserting rigid core piles into cement-soil pile piles. This article briefly introduces the structure, working mechanism and calculation method of cement-soil composite piles. Cement-soil composite piles with low cost, high carrying capacity, is suitable for soft ground reinforcement of a new type of pile
