一、概述桥梁墩台深埋基础計算的研究是一个很有意义的課题。笔者曾借1963年铁路标准設計通讯第9期(以下簡称标設通訊)介紹过苏联对于桥梁墩台深埋刚性基础考虑固着影响的新計算方法。該方法仅适用于埋置换算深度αh小于及等于2.5的基础(这里:h——自冲刷綫算起的基础实际埋置深度,α——基础变形系数,α=((mbp)/(EI))~(5/1),bP——基础的計算寬度;EI——基础的抗弯刚度;E——材料弹性摸量;I——基础的平均轉动惯矩;m——表示基床系数随深度变化的比例系数)。因为根据苏联进行的许多試驗和理論計算的研究証明。当αh≤2.5时倘把基础視为具有无穷大的刚度,将它与考虑基础实际刚度的情况进行比較,二者的水平
First, an overview of the bridge abutment deep foundation calculation of the study is a very meaningful issue. The author introduced the new calculation method of the influence of the Soviet Union on fixing the deep rigid foundation of the bridge piers and abutments by reference to No. 19 of the Railway Standard Design and Communication, 1963 (hereinafter referred to as standard communication). This method is only applicable to foundations where buried depth αh is less than or equal to 2.5 (where h is the actual buried depth from the scour line, α is the base deformation coefficient, α is (mbp) / (EI )) ~ (5/1), bP - the basis of the calculated width; EI - the basis of the bending stiffness; E - material elastic modulus of touch; I - based on the average moment of inertia; The coefficient of bed coefficient with depth changes). Because many experiments and theoretical calculations based on the Soviet Union proved. When αh≤2.5, if we regard the foundation as infinity stiffness and compare it with the actual stiffness of foundation, the level of both
