Abstract:
Compression modulus Es is one of the physical and mechanical
indexes of soil, and it is also an important index for foundation settlement
calculation. The traditional method is to give the curve e-p for manual search [p1,
p2] and[e1, e2], then calculate the compression coefficient av=-Δe/Δp, and then
calculate the compression modulus Esv=(1+e0)/av. In this paper, cubic spline
function is established by using experimental data (p, ln(h)). On this basis, the
APP program is compiled with Android MFP language as a tool to calculate the
tangent compression modulus Es of any point and secant compression modulus
Esv of any interval on the mobile phone.
压缩模量Es 是土的物理力学指标之一,也是地基沉降计算的重要指标。传统的方法是给出e-p 曲线图进行人工查取[p1,p2]及[e1,e2],然后计算压缩系数av=-Δe/Δp,再计算压缩模量Esv=(1+e0)/av。本文利用实验数据(p,ln(h))建立三次样条函数。在此基础上,以安卓系统MFP 语言为工具,编制了APP 程序,实现了在移动手机上计算任意点的切线压缩模量Es 及任意
区间的割线压缩模量Esv。
