Study on the Design Parameter of Bearing Capacity in Composite Foundation with Cement Powder Spraying Pile
-
摘要: 通过模型试验,研究道路工程中水泥粉喷桩处理软土地基时桩间土强度的变化情况,在考虑桩间土强度变化规律的基础上,对工民建规范中复合地基承载力标准值公式中的一些系数提出了修正,可供道路工程粉喷桩复合地基设计时参考。Abstract: Through model experiment, researching the strength variation of the inter-pile soils when the cement powder spraying pile is used to consolidate the highway soft foundation,amending some parameters in bearing capacity formula of the cement powder spraying pile composite foundation at the industrial and civil construction code, making reference for the cement powder pile composite foundation design in the highway construction.
