一、河道开挖断面积计算程序本程序适用于河道疏拓、各种渠道开挖的土方工程量计算。它的特点是,只要输入实测断面的原始数据就可计算出施工水位(根据施工季节拟定)以上、以下及左岸、右岸的开挖断面积,作计算土方,堆土规划及施工管理的依据。(一)计算公式首先将标准断面数据换算成一组直线方程:y_1=K_iX+C_iK_i_C_i——直线方程的斜率和截距,它们与座标 x、y 有关,并按下式计算:Ki=B_(i+1)-B_i/A_(i+1)-A_1 C_i=B_i-K_iA_i式中 A_i 和 B_i——标准断面第 i 点转折点平距(即 x)与高程(即 y)。同理,将实测断面数据(实测断面与标准断面采用相同的座标系)也换算成一组直线方程:
First, the river excavation area calculation program This procedure applies to the river dredging, excavation of various channels of earthwork calculation. Its characteristic is that as long as the original data of the measured section are inputted, the excavation sectional area above, below and on the left bank and right bank can be calculated for the calculation of earthwork, soil dumping planning and construction management based on the construction water level (according to the construction season). (1) Calculation Formula First, the standard section data is converted into a set of linear equations: y_1 = K_iX + C_iK_i_C_i - the slope and intercept of the linear equation, which are related to the coordinates x and y and are calculated as follows: Ki = B_ where A_i and B_i are the horizontal distance (ie, x) and elevation (ie, y) of the ith turning point of the standard section. Similarly, the measured cross-section data (the measured cross-section and the standard cross-section with the same coordinate system) is also converted into a set of linear equations:
