| 摘 要： | 位于复杂地质条件和环境条件下的深圳汝南大厦在基坑支护的施工过程中出现钻进困难,必须重新选择基础工程施工方案.结合场地特殊地质和环境条件在对人工挖孔桩、换填法、树根桩法、旋喷桩复合地基等8种基础工程施工方案进行分析与优选的基础上,借助模糊决策理论进行方法优选验算,最终选定了人工挖孔桩加部分钻(冲)成孔灌注桩的方案.采用该方案在深圳市汝南大厦的施工实践表明其施工效果良好.

| Abstract: | Drilling handicap occurs in the course of excavation of Runan high-rise building in Shenzhen, which located in complicated geological condition and circumstance. Such eight foundation engineering construction schemes as manpower dig pile, replacement method and rooting piles are discussed and analyzed under special geological condition and circumstance. In virtue of optimize and checking computations by fuzzy decision theory, the scheme of manpower dig pile and part drilling bored pile is finally chosen. Also base and effect are dissertated. Successful practice of Runan high-rise building demonstrates that the effect of chosen scheme is excellent. |
