1引言库仑土压力理论最早是由库仑提出来的,迄今已有200多年的历史。理论简单实用,虽然有一些简化和不足,甚至力学上存在弯矩不平衡的遗憾,但一直被工程界采用。笔者近十年来,由于在大学教学的原因,需要给学生讲述此理论,并需要给出正确的力学解释,然而在教学实践中发现了一些问题,便对原传统理论进行了一些思考,并撰文“对
1 Introduction Coulomb’s theory of earth pressure was originally proposed by Coulomb, so far, more than 200 years of history. The theory is simple and practical. Although there are some simplifications and shortcomings, there is even regrettable moment imbalance in mechanics, but it has been adopted by engineering circles. In the past ten years, due to the reason of teaching in university, I need to explain this theory to the students and need to give the correct mechanics explanation. However, some problems have been found in the teaching practice, and some thoughts on the original traditional theory have been made. ”Correct
