直接求解满足柱对承台整体冲切承载力要求的承台最小厚度

The Direct Method of Solving Pile-cap's Minimum Thickness Under Column that Satisfies the Punching Capacity Requirements

工程中一般通过试算确定承台厚度。满足柱对承台整体冲切承载力要求的承台最小厚度可以通过解一元三次方程直接求解,并以MATLAB为平台编制了程序,通过手算复核电算求解结果很可靠。

Trial pilot calculation is usually used in engineering to determine the thickness of pile cap. This paper provides a direction solution to determine the minimum thickness of pile cap that meets the overall punching capacity requirement, by solving a cubic function, a program based on MATLAB was also developed for solving the cubic function, the accuracy of this direct solution was verified by hand computation showing the result with a great reliance.
