近几年来,苏联学者和工程师们在改进挡土墙的计算方法和结构处理方面做了大量工作。但是,已提出的所有方法都没有考虑提高边坡稳定性和降低挡土墙上的土压力,共中包括土的内摩擦力的增大和土颗粘间粘聚力的提高问题。解决粘土地区边坡和挡土墙稳定问题的一种新方法是利用深钻孔对粘土进行深层焙烧。土体热加固处理的结果增加了土的内摩擦角和粘聚力,提高了焙烧土体与下卧岩土层的摩擦系数。若将边坡土加以焙烧形成挡墙,则这种焙烧土挡墙可用合适的尺寸做成各种最合理的形状,并能以任意角度倾向被支撑的土体。由焙烧土做成的边坡可以是垂直的,或是具有最小的倾斜度的。
In recent years, Soviet scholars and engineers have done a great deal of work in improving the calculation methods and structural treatment of retaining walls. However, all of the proposed methods do not consider increasing slope stability and reducing earth pressure on retaining walls, including the increase of internal friction of soil and the increase of cohesion between soil particles. A new method to solve the problem of stability of slope and retaining wall in clay area is to deeply sinter the clay by deep drilling. The results of soil heat treatment increase the internal friction angle and cohesion of soil, and increase the friction coefficient of roasted soil and the lower soil layer. If the slope soil is roasted to form a retaining wall, the calcining earth retaining wall can be made in any suitable shape to the most reasonable shape and can be inclined at any angle to the supported soil. Slopes made of roasted clay may be vertical or have the smallest slope.
