摘要:
工程勘察三轴试验的总应力强度指标的计算,运用解析几何原理导出任意两个应力圆公切线 切点坐标计算公式,尤其是直接计算切线斜率。各切点通过线性回归建立合切线包线)的直线方程,进 而计算凝聚力Cu和摩擦角φu。采用数据直接计算方法,替代了以前手工图解或计算机交互图解,计算 速度快,精度高。
Abstract:
In order to calculate the intensity of general-stress in tri-axis test in geotechnical investigation , the author uses cartesian geometry principle to derivate calculation functions of common tangent points coordinates of every circle by the common tangent line .Especially , the slope tangent line is calculated directly .With regard to all of tangent points , the linear regression method is used to derive the equation of the tangent line , and then to calculate the coacervation force Cu and the friction angle φu of the soil.This direct calculating method may take place of the illustration methods by hands or interactive illustration method on the computer , and is faster and may take more precise .
