【摘要】 本文通过结合实际工程案例,对比分析了加筋土挡墙与重力式挡墙在山区水厂高填方工程中的应用。借助于三维有限元计算,分析了两种支护结构的施工过程,其结果表明加筋土挡墙与传统重力式挡墙相比,其安全系数较高,支护结构位移与土体位移较小,造价较低,基底反力较小。同时,在加筋土挡墙在施工过程中,安全系数呈现先增后减的规律;当加筋土挡墙的高度与墙顶原边坡高度接近时,安全系数达到最大值。本文总结了加筋土挡墙在山区水厂高填方工程中应用的优势与注意事项,根据有限元计算对加筋土挡墙方案进行了优化,为类似工程提供参考与借鉴。更多还原

【Abstract】 Combined with practical engineering cases,the application of the geogrid-reinforced retaining wall and gravity retaining wall in the high fill project in water plant were compared and analysed in this paper.By the three-dimensional finite element calculation,the construction process of these two structure schemes were analyzed.The results showed that compared with the traditional gravity retaining wall,the geogrid-reinforced retaining wall has greater security,smaller displacement,lower cost and lower basal reaction force.In the construction process,the safety factor of grogrid-reinforced retaining wall increases first and then decreases.When the height of the reinforced soil retaining wall is close to the height of the original slope on the top of the wall,the safety factor reaches the maximum.This paper summarized the advantages and cautions of the geogrid-reinforced retaining wall applied in the high fill project in water plant and optimized the geogrid-reinforced retaining wall according to the finite element calculation,which could provide reference for similar projects.更多还原
