摘要

摘要: 嵌岩桩的侧摩阻力发挥不但与桩端支承与桩周土性有关,同时还受其他众多因素影响。根据同一场地桩周土性差异不大,而桩底岩土强度有较明显区别的两根达极限承载状态的嵌岩桩试桩资料,分析桩周土侧阻发挥过程。结果表明:对于长径比较大的嵌岩桩,桩周土极限侧阻大小随桩端支承条件不同而改变,且侧阻沿桩身分布呈现两头大中间小的特点,此外上部土层对桩身中部土层的侧阻发挥有一定的影响。

Abstract: The shaft resistance of socketed pile is affected with not only the strength of the rock at the end of piles but also the kinds of soil around the piles. Based on the field static load experiment on the large diameter rock socketed piles and the strain testing of them, the process of the exertion of the shaft resistance along the pile is analysed. The outcome shows that the ultimate shaft resistance of the pile is influenced by bearing condition of the piles, and the character of shaft resistance distribute along pile presents large in both sides while little in the midst. Furthermore, the exertion of shaft resistance of the earth lies in the middle of the pile is affected by the stratum overlaid.
