以往习惯对T台前墙所受的锥体土压力简称为前墙土压力。而埋式桥台旁侧填土的滑动土楔体因受桥台限制,故其产生的土压力称为有限土压力。这两种土压力,现有的计算公式比较繁复,作者将其计算方法中的优点汇集一起并作推导,得出上述土压力的计算另法,优点为概念清晰,计算简单。根据推论,其它形式之土压力也可用另法计算。一、T台前墙土压力 In the past, it was accustomed to the conical earth pressure suffered by the front wall of the T station, which is referred to as the earth pressure of the front wall. However, because of the abutment limitation, the sliding earth wedges beside the buried abutment abutment are called finite earth pressure. The two kinds of earth pressures, the existing formula is more complicated, the author of the calculation methods together and bring together the advantages derived from the calculation of earth pressure another method, the advantages of a clear concept, the calculation is simple. According to corollary, other forms of earth pressure can be calculated by alternative method. First, T station front soil pressure
