摘要
针对广西地区建筑工程中典型泥岩的基本类型和特点,设计了三组嵌岩桩模型试验.试验表明,嵌岩桩在泥浆浸泡后嵌岩段侧阻力下降,泥浆浸泡时间越长,嵌岩段侧阻力下降越大,泥浆浸泡对嵌岩桩破坏范围也有影响;成桩后随放置时间增长,嵌岩段侧阻力先降后升,认为在软岩地区要重视泥浆对嵌岩段侧阻力的影响.
Based on the research of classification and feature of typical mudstone in some projects in Guangxi area, three groups of model test on rock-socked pile are designed. It is shown that the side resistance of rock-socked part of pile foundation becomes low when poured by slurry, the longer it is soaked in slurry, the lower of the side resistance of rock-socked part, the failure scope is also affected by slurry, piles that are placed in different periods have different side resistance of rock-socked part, with the time going, the side resistance of rock-socked part of pile fist descends and then increases, so it is essential to give weight to the effect of slurry to side resistance of rock-socked part of pile foundation.
