| 摘 要： | 在由抗冲切验算确定了基础高度以后,若基础高度较大可能要分成2～3个台阶,每个台阶的高度和宽度一般采用平均分配的办法;通过分析认为,采用平均分配的办法是不合适的,可以通过直接求解得到上层台阶的最小平面尺寸,所有大于该最小平面尺寸的尺寸都能满足台阶的冲切要求,并以MATLAB为平台编制了程序,供大家使用。

| Abstract: | To determine the bottom area of the column＇s rectangle extended foundation, the checking computation of the ground＇s carrying capacity must be conducted. Usually a trial-calculation is adopted to determine the foundation＇s bottom area and the times of the trial-calculation depends on experiences. Therefore, the trial-calculation is not very fit for the practical calculation in the engineering project and in teaching. A three-step way without multiple trial-calculation is put forward. No matter the column is in a state of one-way eeeentric or two-way eccentric, and no matter the degree of its eccentricity .After the three-step calculation, An economic and reasonable bottom area ofcolumn＇s rectangle extended foundation can be determined. |
