1) platform supported type relief
承台式卸荷
2) relieving board
卸荷台
1.
Based on the educing of the minimal capsizing moment and the minimal earth pressure by Rankine’s earth pressure theory,the rational position of retaining wall relieving board was found:the upright distance from relieving board to the external surface of filling soil is one-third to one-second times of retaining wallh ighness.
利用朗肯土压力理论,通过对最小倾覆力矩和最小土压力的求解,得出了挡土墙卸荷台的合理位置:在距填土表面的垂直距离为墙高的1/3～1/2范围内。
3) unloading plat
卸荷平台
1.
The paper introduces the calculation method of a mixed retaining wall using cement mixing pile and unloading plat by grouting in back wall, and its application in excavation is analysised.
本文介绍了水泥搅拌桩重力式挡墙与墙后注浆卸荷平台组合支护的计算方法,及其在基坑工程中的应用。
4) the load carrying capacity of a unloaded earth arch
卸荷拱承载能力
5) relieving retaining wall
卸荷式挡墙
1.
Through comparison of force balance analysis between cantilever and relieving retaining wall,it shows that,at the same height,relieving retaining wall suffers smaller bending moment at the lowest part of the wall than cantilever retaining wall.
通过对悬臂式挡土墙与卸荷式挡土墙受力分析比较,可以看出同样高度的卸荷式挡墙较悬臂式挡墙在挡墙墙壁根部所受弯矩要小,这样可以减小挡墙墙壁的壁厚及配筋,同时也可以减小倾覆力矩,即可以减小挡墙底板宽度。
