摘要
介绍了一种处理地面横坡线的方法 ,该方法利用最小二乘原理将地面线处理成双向横坡形式 ,能够在减少计算量的同时又满足所需精度 ,是目前采用比较多的一种方法。文中还总结了不同断面形式的土石方量计算公式。根据文中介绍的处理方法和给出的判断条件及计算公式 ,在计算机中编制出程序进行实例计算 ,结果证明该方法简单易行 ,并具有很强的可靠性。
This paper presents a method of dealing with cross section which makes use of the least square method. This method is very important in highway profile optimization design because it could simplify the primitive data and reduce the amount of calculation. The paper also lists four kinds of cross section and their conditions and formulas. Based on the method and algorithm, the author has developed the computer programs in VC ++ 6.0 to calculate the cubic meter of earth and stone. It has been proved that this method is easy and feasible.
