本文从理论上及应用上论证的主要问题; 1、填土破裂角有一定范围。 2、内部破裂面产生的条件。 3、简化计算法与朗肯公式有何异同。 4、对称第二破裂面产生条件及附合简化计算方法假设。 5、通过墙角铅垂平面上摩擦力的求解和对建筑物安全的影响。 6 有些情况用简化方法计算将遗成严重浪费。 7、有些情况用简化方法计算将造成严重危险。而不是许多文献中介绍的仅偏于安全。 8、墙与填土的摩擦角δ值,对建筑物安全影响巨大。必须计算。而不是影响很小不必考虑。 9、δ值愈大建筑物愈安全及增大δ值的有效方法。 10、向外倾斜较大的挡墙应以最不利情况设计。
This paper proves the main problems in theory and application; 1, there is a certain range of fill crack angle. 2, the conditions of the internal rupture surface. 3, Simplify the calculation method and Rankine formula What are the similarities and differences. 4, symmetry of the second rupture surface conditions and attached to simplify the calculation method assumptions. 5, through the corner of the vertical plane to solve the friction and the impact on the safety of buildings. 6 In some cases, a simplistic calculation will result in serious waste. 7, in some cases a simplified method of calculation will pose a serious risk. Not just the security described in many documents. 8, the friction angle between wall and fill angle δ, a huge impact on the safety of buildings. Must be calculated. Instead of having minimal impact, do not worry about it. 9, the larger the δ value of the building more secure and increase the value of δ effective method. 10, outward tilt larger wall should be the most unfavorable situation design.
