对属于地基处理 (旋喷法 )和桩基工程 (人工挖孔 )的两种工艺进行了有效的组合 ,给出了两种施工工艺适用的场地土质条件、工程条件、水文地质条件 ;设计了两种组合模型 ,分别论述了模型的组合条件、组合理论、模型设计 ;并根据沈阳城区的岩土工程条件 ,对组合桩的承载力、沉降量、沉降差等计算或判定 ,以及有关参数的选择做了说明 ,绘制了施工流程图 ;对这两种类型给出了工程实例印证。
The two processes that are part of the foundation treatment (spinning) and the pile foundation (manual digging) have been effectively combined, and the site’s soil conditions, engineering conditions, and hydrogeological conditions for the two construction processes are presented; Two kinds of combinatorial models discuss the combination conditions, combinatorial theory, and model design of the model respectively. According to the geotechnical engineering conditions in the urban area of Shenyang, the calculation or determination of the bearing capacity, settlement, settlement difference, etc. of the composite pile, and related parameters The selection was made and the construction flow chart was drawn; the engineering examples were given for the two types.
