一、概述公路桥的桥台一般都视为刚性挡土墙,其所受的土压力一般用库仑土压力理论计算。实际上,这与桥台真正所受的土压力相差甚大。公路桥台形式很多,而且构造、式样差别也很大。迄今为止,尽管也曾有人提出过一些具体对象桥台的计算方法(如U形桥台 First, an overview Bridge abutments are generally regarded as rigid retaining wall, the earth pressure suffered by the Coulomb earth pressure theory is generally calculated. In fact, this is quite different from the earth pressure on the platform. Highway abutment form a lot, and the structure, style is also very different. So far, though some people have also proposed some calculation methods of abutment (such as U-shaped abutment
