复杂土层中采用挖孔桩墩基础的实用技术

Practical Technology of Using Excavated Pile Pier Foundation in Complex Soil Stratum

根据工程实践 ,论述在不同层理构造类型的复杂土层中 ,桩墩基础采用短段掘砌法施工时 ,以“复合工法”处理桩墩成孔中的关键技术问题。该工法处理的效果可靠 ,施工简便易行 ,并以软土和冶金渣等复杂地基为例 。

According to the project practice, the paper states the key technical problem in the excavated hole of pile pier treated by 'composite working method', when pile pear foundation adopts the construction method of digging and building by short sector in different stratification structural types of complex soil stratums. The working method has the reliable treatment effect, and its construction is easy and feasible. Taking the complex soil foundation such as soft soil and metallurgical slag etc. as an example, the paper illustrates the actual application.
