摘要
针对传递系数法在滑坡推力计算中存在的不足,根据刚体极限平衡理论,以分块极限平衡法为基础,推导出一种改进的传递系数法的递推公式及累计求和表达式,并结合工程实例与传统的传递系数法进行了对比分析。结果表明,改进的传递系数法计算出的结果偏小,与实际情况吻合。
Aiming at the shortcomings of transfer coefficient method for calculation of landslide thrust, according to the rigid limit equilibrium theory, based on the block limit equilibrium method, the author deduces recursive formula and accumulated sum expression of improved transfer coefficient method. Combined with the project example and comparison of traditional transfer coefficient method, the results show that the consequence obtained by improved transfer coefficient method is small, which is consistent with the actual situation.
