在乌拉尔等地区广泛采用各种型式装配式钢筋混凝土薄壳基础,且有效地应用薄壳建造各种挡土构筑物。编制了三种装配式钢筋混凝土挡土墙图集,它们的正面墙板采用了双曲和锥面薄壳(图1)。计算中填土和地基土取用具有如下计算特征的砂:内摩擦角为30°,单位体积重量为1.8吨/米~3,基础底部对土壤的摩擦系 Various types of fabricated reinforced concrete thin-shell foundations are widely used in Urals and other regions, and thin shells are effectively applied to construct a variety of retaining structures. Three atlases of prefabricated reinforced concrete retaining walls were prepared, and their front wall panels were made of hyperbolic and tapered shells (Figure 1). Calculate the fill and foundation soil to use the sand with the following characteristics: internal friction angle of 30°, weight per unit volume of 1.8 tons/m3, and friction at the bottom of the foundation.
