目前,我们经常采用挡土墙的型式有:后倾式、重力式、钢筋混凝土板桩、混合式等。虽然,各种类型的挡土墙结构都具有自己的特点,但工程的材料消耗与造价指标都是比较高的。特別是在高度较大的挡土墙设计中矛盾更为突出。因此,寻求高挡土墙的新型式已成为设计人员的新课題。在一九六○年的国外杂志上,介绍了高挡土墙的新型式(见图1、图2)。我院一九六○年在上海市中山环路苏州河桥接坡工程设计中,采用了拱型薄壁挡土墙(图3),通过十三年的使用证明,效果较好。而且在材料消耗与造价指标等方面都有了显著的降低。目前双
At present, we often use the retaining wall of the type are: backward, gravity, reinforced concrete sheet pile, hybrid and so on. Although various types of retaining wall structures have their own characteristics, but the project material consumption and cost indicators are relatively high. Especially in the design of tall retaining walls, the contradictions are more prominent. Therefore, the search for a new type of high retaining wall has become a new issue for designers. In a foreign magazine in 1960, a new type of high retaining wall was introduced (see Figure 1 and Figure 2). In 1960, our hospital adopted arched thin-walled retaining wall (Figure 3) in Suzhou River Bridge Slope Engineering Design of Zhongshan Ring Road in Shanghai. After 13 years of use, it proved to be effective. But also in material consumption and cost indicators have a significant reduction. Currently double
