在实践中经常出现桥台基础及挡土墙基础的水平位移和倾斜现象。这说明有必要对目前采用的计算方法进行修正。然而无论是对上述建筑物稳定性原有计算方法进行修正,或是建立新的计算方法,均须具有合理的根据,结合考虑土力学发展的现状同时要经过实践(实验)的验证。然而鲁氏所撰《论引线路堤对桥台挡土墙基础的水平压力》”一文中的建议根本谈不到上面的要求。鲁氏试图修正引线路堤对桥台和挡土墙基础部份的水平压力数值。引线路堤的影响以均匀分布荷载P=XH(X是土的容重,H是引线路堤高度)。在求水平压力数值时还引用了线性均匀介质理论。但基础后边的摩擦力却未考虑。同时把这一问题当作
In practice, the horizontal displacement and inclination of abutment foundation and retaining wall foundation often occur. This shows the need to amend the current calculation method. However, it is necessary to correct the original calculation method of the stability of the above-mentioned buildings or to establish a new calculation method, and should be verified by practice (experiment) in combination with considering the current situation of soil mechanics development. However, Lu’s article “On the horizontal pressure on the abutment retaining wall on the basis of the lead embankment” simply can not talk about the above requirements.Ru’s attempt to amend the lead embankment on the abutment and retaining wall foundation The effect of the lead embankment is based on the uniform distribution of load P = XH (X is the bulk density of the soil and H is the height of the lead embankment.) The theory of linear homogeneous media is also used in the calculation of horizontal pressure values. The friction has not been taken into consideration
