现场测试结果表明，台背土压力大致呈“抛物线型”分布，与库仑土压力理论的线性分布不同。
The results of field test indicate that the earth pressure of abutment, different from linear distribution of Coulomb's, acts as parabolic type.
比较结果表明土压力与实测结果吻合较好，采用库仑土压力理论计算存在诸多不安全因素。
It is demonstrated that the calculating results by this thesis's method better safety and agreement with those of the experiment than those by Coulomb's theory.
