摘要
本文以地貌单元、地层时代和地层组合为基本要素,根据我国广泛分布的地貌单元的时代———地层组合特点,将深基坑的地质条件划分成六种常见的、有代表性的组合类型。进而对这些不同类型地质条件下深基坑的变形破坏机制类型、其主要岩土工程问题和支护形式进行了概括。文中对“与地下水渗透破坏有关的深基坑变形破坏机制和主要岩土工程问题”作了专门论述。最后提出了深基坑工程设计的一些宏观控制念。
The author summarized 6 most common and typical associations of deep foundation trenches in China, based on geographic unit, stratigraphic age, and strata association. Furthermore, the author discussed their breakdown, main rock engineering problems and supporting system. The ground water related breakdown of the deep foundation trench has been studied in detail. Some macro -control conception for deep foundation design is also proposed in the paper.
