1962年11月在北京召开讨论“挡土墙标准设计原则”时,曾如下几个问题: 1)新法(即桥涵設計规范规定方法)及旧法(原来采用于挡墙计算的方法)倾倒安全系数在挡土墙设计中的运用和比较。 2)傾斜基底情况下,新、旧法倾斜安全系数的此较及其与平基底情况下傾倒安全系数的比較。 3)倾斜基底面土承受的应力,应按倾斜基底面拆抑或倾斜基底的水平投影面計算?二者何属不利的情况?
When discussing the “Standard Design Principles of Retaining Wall” in Beijing in November 1962, the following questions were asked: 1) The safety factor of dumping (ie, the method prescribed by the code for design of bridges and culverts) and the old method Application and Comparison of Retaining Wall Design. 2) In the case of tilting the base, the comparison between the safety factor of the new and the old method and the safety factor of the dumping under the condition of the flat base is compared. 3) Tilting the stress on the base soil should be calculated by tilting the base surface or tilting the horizontal projection plane of the base. What are the disadvantages of both?
