摘要

摘要: 滑坡推力是抗滑桩设计推力的重要依据,工程中通常使用剩余推力法来计算滑坡推力。为了比较准确合理地计算出抗滑桩的设计推力,提出了在剩余推力法基础上的一种新的抗滑桩设计推力取值方法。分析极限平衡状态下和工程安全要求下各条块的剩余下滑力,选择合理的桩位,使得抗滑桩位于滑坡体的抗滑段;然后调整桩后滑体的剩余下滑力,其调整量一方面保证桩前桩后滑体满足工程安全要求,另一方面则作为抗滑桩设计推力的修正依据,其过程由程序实现。通过实例证明了该方法的合理性。同时对今后抗滑桩设计推力的合理取值提供了参考作用。

Abstract: The landslide thrust is the important evidence for the designed thrust of anti - slide p ile. It is often cal2 culated with the residual thrustmethod. On the basis of residual thrustmethod, a new method to find the designed thrust of anti - slide p ile is p roposed for an accurate and reasonable result. On the condition of limit equilibrium state and safety requirement, the residual thrust is calculated and reasonable p ile position is determined to make it locate the anti - slide segment of landslide. Residual thrust of landslide lies behind the p ile is adjusted to ensure not only that adjustment quantity can meet safety requirement, but also it can be modify on the basis of the designed thrust of anti - slide p ile. All of this consideration is realized with p rocedure. The method is verified with exam2 p les. It also p rovides reference function for reasonable value of the designed thrust of anti - slide p iles in the future.
