土壳式挡土墙是一种采用新颖工艺的挡土结构,由锚固在被动土区的薄壳结构组成。土壳是由波纹形钢板弯成U形体作为单元容体,U形板由中央拱、两侧直壁和壁端增设的凸缘组成。敞开口朝向挡护土体,再在单位容体内分层夯实填土,使各结构单元与土体协同工作,建成整座土-壳式挡土墙。土壳式挡土墙的半圆柱形壳腔内填土重量是墙体稳定的有利因素,随着拱体效应的形成,充填紧
The soil-retaining retaining wall is a kind of retaining structure adopting a novel process, which consists of a thin shell structure anchored in the passive soil zone. The earth shell is bent into a U-shaped body by a corrugated steel plate as a unit volume, and the U-shaped plate is composed of a central arch, two straight walls on both sides, and an additional flange at the wall end. The open mouth is facing the retaining soil, and the soil is tamped and tamped in the unit volume to enable the structural units and the soil to work together to build the entire soil-shell retaining wall. The weight of the soil filled in the semi-cylindrical shell of the retaining wall is a favorable factor for the stability of the wall. With the formation of the arch effect, the filling is tight.
