| 中文摘要: |
| 《建筑边坡工程技术规范》中计算主动土压力公式较为冗长、理解难度大，不易被人掌握。本文基于库仑土压力理论，将墙体与墙后填土之间的力以综合内摩擦角考虑后，推导得出了优化计算主动土压力的通用解析式。通过算例验证表明通用解析式和规范公式计算主动土压力结果近似；在相同条件下，规范中土压力公式均可由通用解析式推导得出。与规范公式相比，通用解析式具备原理清晰易掌握、公式简洁明了、计算过程简单快捷的特点，计算精度能满足工程要求，在实际工作中具有较好的使用价值。 |

| Development, Zunyi 563000, Guizhou, Chian)The formula for calculating active earth pressure in “technical code for building slope engineering” is lengthy and difficult to understand, so it is not easy to master. Based on the Coulomb’s earth pressure theory, the general analytical formula for the optimal calculation of active earth pressure is derived after considering the force between the wall and the fill behind the wall as the comprehensive internal friction angle. The results of calculation examples show that the results of active earth pressure calculated by the general analytical formula and the code formula are approximate; Under the same conditions, the earth pressure formula in the code can be derived from the general analytical formula. Compared with the standard formula, the general analytical formula has the characteristics of clear principle, simple formula, simple and fast calculation process, and the calculation accuracy can meet the engineering requirements, which has good application value in practical work. |
