摘要
设计滑坡推力是滑坡治理设计的重要依据。本文通过建立剩余推力法计算滑坡推力的力学模型,给出了在不同荷载作用下的滑坡剩余推力表达式,同时就与设计推力关系密切的安全系数的选用及岩土强度指标c、Φ值的选用两方面进行了探讨,最后对抗滑桩的设计载荷的确定作了比较详细的探讨,考虑了设桩后对桩后土体的反力,给出了确定抗滑桩设计参数的方法。
The design thrust is the key basis for landslide treatment design.The expression is gived on landslide residual thrust under various load by establishing mechanics model of landslide thrust calculation on residual thrust method in this paper,meanwhile,the two aspects are studied that are closely connected with design thrust,they are safety factor and geotechnical strength index c、Φ,finally,the anti-slide pile＇s design thrust is studied in detail,the soil counter-force behind the pile is took into account and the method is given that could define design parameter of anti-slide pile.
