【摘要】 通过分析现有预应力锚索抗滑桩力学计算模型的特点,找出存在的问题,提出了改进的滑坡推力和桩前土体抗力的分布图形,分析了预应力锚索在锚索桩中的工作机理和预加固作用及其在力学建模中的考虑方法,提出了锚索桩改进的建模方法并通过工程实例对改进方法和原有方法进行比较,论证了改进方法的合理性。更多还原

【Abstract】 Through the analysis of character of mechanic model of pre-stress anchored anti-slide pile that people are accustomed to u-sing at present, some deficiencies are found out and the improved distribution function of the landslide-thrust and the resistance of soil or rock are provided with a chart, the working principle of pre-stressed anchor and it’s use in the mechanic model building process also is studied. The improved method for mechanic model building is presented and the result of new method is compared with the result of old one based on the use of practical engineering. The rationality of improved method also is discussed.更多还原
