台阶式加筋土挡墙土压力计算研究

Study on Calculation Methods of Tiered Reinforced Earth Retaining Wall

土压力计算是加筋土挡墙设计的基础。阐述了实际设计中常用的简化计算方法和传统弹性力学计算方法,但是根据以上两种方法得到的计算值与实测值相差甚大,因此在实际设计中很难得到广泛推广。借鉴了上面两种方法的不足之处,提出了一种计算台阶式加筋土挡墙土压力的新方法,用该方法得到的计算值与实测值吻合的较好。

The calculation of earth pressure on reinforced earth retailing wall is the basis of design on retaining wall. The practical simplified method, as well as the traditional one based on elastic mechanics, is described in the paper. But the values calculated by the two methods above are far away from the testing data, which makes it difficult to put into use widely. Combined with the two methods above, a new method is proposed to calculate the earth pressure on tiered reinforced earth retailing wall. The values calculated by the new method can accord well with the testing data.
