摘要
基础工程钻孔灌注桩及其承台一次完成砼灌注，是一类在施工技术特点和施工难度方面具有一定代表性的砼工程。对此类工程进行施工技术问题的理论探讨是完全有必要的。本文以工程为例进行了此类工程施工技术理论研究，并且提出一些对实际生产具有指导性的观点。
To the infrastructure engineering the drilling pile and its bearing stage ispoured into conrete once,which is a kind of the representative engineering in the side ofthe constructional technology feature and constructional difficulty.To this kind of theengineering,it is completely necessary for inquiring into the theory on the problems of theconstructional technology.This literary researches the constructional technology theoryto the kind of the engineering and puts forward the same useful standpiont to the practicalproduce by way of the engineering.
