【摘要】 从水泥深层搅拌桩加固体特性出发,分析了水泥搅拌桩强度影响因素,研究了深搅水泥土的声学特性和强度特征及其规律,给出了有关强度与波速的数学表示,在分析了理论可行性和实际可操作性后,认为有条件地采用动测方法进行对水泥搅拌桩复合地基质量评价是一个适合大面积测试、经济的方法。更多还原

【Abstract】 The strength effecting factors of cement deep mixing pile, the acoustics characters and strength rules of deep agitating strengthening soil with cement have been studied in this paper. The mathematical relations between strength and wave speed are given after analysis of theoretical feasibility and practical maneuverability. The dynamic survey method conditioned used is a economical and convenient way for cement agitating complex foundation quality evaluation.更多还原
