摘　　要：传统的土压力理论计算繁琐、工作量大且手工计算不够精确。利用坐标判别法,将墙后土体及墙身面积分成若干个三角形,通过坐标可快速准确地计算出墙后土压力及土压力作用点位置。结合计算机编程,大量节省计算时间和工作量,提高了工作效率。Traditional calculation theory of soil pressure is complex, heavy loaded and not accurate enough by manual calculation. The soil mass behind wall and the wall body are divided into several triangles using coordinate judgment system. Then soil pressure behind wall and the position of pressure point can be calculated rapidly and accurately using coordinates. Combined with computer programming, this method largely saved calculation time and workload and improved working efficiency.
