| 摘 要： | 根据土力学原理,探讨了气候影响下非饱和膨胀土对挡墙的土压力计算方法和过程,根据土体的基质吸力,利用土体弹性平衡,求取土体裂缝开裂深度,将开裂深度范围内土体作为超载作用在下卧土层上,利用极限平衡条件,求取挡墙土压力的数值,同一挡墙不同时间的土压力是不同的。

| Abstract: | According to the principle of soil mechanics. To explore the calculation method and process of earth pressure on the retaining wall with the influence of climate in unsaturated expansive soil. In accordance the soil matrix suction. Using a flexible balance of soil. And earth cracks crack depth is obtained. And the crack depth of soil layer as a overloading role on the next bed soil. The use of limit equilibrium conditions, earth pressure of a wall is obtained, the different time earth pressures of same wall are different. |
