[提要] 在工程實(shí)踐和有關(guān)文獻(xiàn)的基礎(chǔ)上，探討了土壓力計(jì)算公式及其分布模式的普遍形式及其與支護(hù)方式的關(guān)系，提出了用于確定巖土工程參數(shù)的滑裂面調(diào)查法。方法從極限平衡的概念出發(fā)，運(yùn)用工程類比的思維方式，通過調(diào)查滑裂面幾何參數(shù)臨界深度zo和滑裂面傾角自來反演土體抗剪強(qiáng)度c， φ值。
[關(guān)鍵詞] 土楔法 基坑工程 土壓力 分布模式 滑裂面調(diào)查法 巖土工程參數(shù)Basing on engineering practice and relative measure material, soil pressure formula and its distribution regularity are put forward. It is suggested that the distribution mode should be chosen by the supporting pattern.The sliding surface investigation method that is used to judge geotechnical engineering mechanical papameters is presented. The new approach can back-analyze soil shear strength numeral c and φ by investigating geometrical characterstics of the sliding surface ancl with analogy method, basing on limit equilibrium theory, making a profitable try in determining the geotechnical engineering papameters.
Keywords: soil wedge method; foundation pit engineering; soil pressure; distribution regularity; sliding surface investigation method; geotechnical engineering mechanical papameters參 考 文 獻(xiàn)
