土方工程量直接关系到土地开发项目投资预算的科学性。为了比较准确地测算低矮条状土方工程量,以定边县王滩子村土地开发项目排碱沟开挖土方量为研究对象,基于CASS7.0上的地形土方和土堆土方立体模型,选定实测数据中最低高程点所在平面为统一参考计算面,两个模型到参考计算面的体积之差为目标土方量,对低矮条状土方工程量测算方法进行了研究。结果表明:此方法对低矮条状土方量计算具有一定的先进性和实用性,能弥补传统计算方法带来的误差。
Earthwork volume is directly related to the scientific nature of the land development project investment budget. In order to more accurately calculate the amount of low bar-shaped earthwork, the earthwork of the caustic ditch excavated in the land development project of Wangtanzi Village, Dingbian County is taken as the research object. Based on the three-dimensional model of earthwork and mound earthwork on CASS7.0, The plane of the lowest elevation point in the selected survey data is the uniform reference plane, and the difference between the two models to the reference plane is the target earth volume. The calculation method of the low bar earthwork volume is studied. The results show that this method has a certain degree of sophistication and practicability for the computation of low bar-shaped earthwork, which can make up for the error caused by the traditional calculation methods.
