摘要

    摘要
  • 摘要: 在理清不同桩间岩体破坏形式的基础上,对边坡工程中抗滑桩岩拱效应和合理桩间距的确定方法进行了分析,阐明了软质岩体拱效应的形成及演化机理,基于拱轴内力、破坏方式及位置对比分析了岩拱与土拱特性的差异性。在此基础上,建立了悬链线拱轴方程,利用两铰拱原理对岩拱进行了内力计算分析。利用岩体跨中极限平衡条件,建立了拱轴系数m关于桩间距l及拱高f的表达式。同时,利用MATLAB软件对抗滑桩桩合理桩间距进行了探讨。从工程实际中岩拱效应充分发挥及安全经济角度考虑,给出了合理桩间距的选择方案。
    Abstract: Based on the clarification of the failure forms of different rock masses between piles, analyses on rock-arch effect of anti-slide piles and determination method of rational pile spacing in slope engineering project were conducted in the present method. In this paper, the formation and evolution of arching effect of soft rock were illuminated, and the comparative analysis for characteristics of rock and soil arches was carried out based on the internal force, failure mode and position in arch axis. Using the above-mentioned analyses, the catenary arch-axis equation was proposed, and the two-hinged arch theory was adopted to calculate the internal forces of rock arch. Moreover, the expression of arch-axis coefficient m concerning pile spacing l and arch height f was established using the ultimate equilibrium condition in mid-span rock mass. Moreover, the MATLAB software was adopted to assess the rational pile spacing. For practical purposes, the rational pile spacing was given to fully develop the rock-arch effect and meet the requirements of economy. The data of engineering example was used to verify the rationality of the present calculation method. The present method can be referenced for similar engineering designs.
