11.6.1 优点在园形或椭园形的构造物中没有支撑工程时也可施工,它具有很大的优点。所以,当由于一度做了周边的墙在其中进行掘削时,地上、地下几乎可以同时施工。能够配置成曲线的墙时,就是在从来没考虑这样做的构造上也能利用。可是,必须对工程的构造目的是否与该形状的特征相适应进行探讨。这种形状因具有拱作用的效果,对横方向具有较大土压力的构造设计上非常有利。从下例看出能使构造物的尺寸缩小。不论支撑工程的有无,按水平直线布置做的墙,在
11.6.1 Advantages Construction can also be carried out when there is no supporting work in a circular or elliptical structure. It has great advantages. Therefore, when the surrounding wall was once excavated, the ground and the ground could be constructed almost simultaneously. When a curved wall can be configured, it can be used in a structure that has never been considered for doing so. However, it is necessary to discuss whether the purpose of the construction of the project is compatible with the characteristics of the shape. This shape has an arch effect and is very advantageous for structural design with large earth pressure in the transverse direction. The following example shows that the size of the structure can be reduced. Regardless of the presence or absence of supporting works, walls that are arranged along a horizontal straight line are
