加筋挡土墙在地震作用下的数值分析

加筋挡土墙是一种在地震灾害下受影响较小的挡土墙形式,相较于重力式挡土墙,其在地震载荷的破坏下呈现出良好的抗震性能。加筋挡土墙现今已经在工程领域中得到了广泛的应用,但是其缺乏相应的力学研究模型,其动力学理论主要采用的是拟静力法,而拟静力法的应用是在众多的假设条件下进行的,致使以拟静力法所建立的加筋挡土墙动力学分析存在着一定的缺陷性,为解决这一问题可以采用数值分析法对加筋挡土墙在地震作用下的动力学模型进行建立与分析,获取更加真实、可靠的加筋挡土墙动力响应规律。

Reinforced retaining wall is a kind of retaining wall which is less affected by earthquake disaster.Compared with gravity retaining wall,reinforced retaining wall shows good seismic performance under seismic load.Reinforced retaining wall has been widely used in the field of engineering,but it lacks the corresponding mechanical research model,and its dynamic theory mainly adopts quasi-static method.However,the application of the quasi-static method is carried out under many hypothetical conditions,resulting in some defects in the dynamic analysis of the reinforced retaining wall established by the quasi-static method.In order to solve this problem,the dynamic model of reinforced retaining wall under earthquake can be established and analyzed by numerical analysis method,and a more real and reliable dynamic response law of reinforced retaining wall can be obtained.
