上海市浦东新区河道整治工程中的护坡设计和太浦河工程中的护坡设计,都在斜坡顶部设置2米左右高度的直立式挡墙结构。本文不讨论为何在斜坡顶部设挡墙,也不讨论斜坡结构,只研究该直立式挡墙的设计。这种挡墙虽然不过是一种小型的挡土墙结构,然而由于长度达十几或几十公里,其断面尺寸的大小,对整个工程的经济指标却有不小的影响,所以设计安全可靠经济合理的挡墙断面,仍是重要
The slope protection design in the river regulation project of Pudong New Area in Shanghai and the slope protection design in the Taipu River project are all equipped with upright retaining wall structures with a height of about 2 meters at the top of the slope. This article does not discuss why retaining the wall at the top of the slope, nor discuss the slope structure, only to study the design of the vertical retaining wall. Although this type of retaining wall is only a small type of retaining wall structure, the size of its cross-section has a considerable impact on the economic indicators of the whole project due to its length of more than a dozen or tens of kilometers. Therefore, the design is safe and reliable Economical wall sections are still important
