土方量计算方法研究与应用

工程项目土方量计算的准确性直接关系到项目投资和预算等经济利益,所以计算土方量对于工程项目来说是至关重要的。为了更好地适应工程项目的需求,提高土方量计算的准确性,研究比较土方量计算方法以寻求最佳解决方案是非常有必要的。常用的土方量计算方法有方格网法、断面法、等高线法和DTM法。本文对这4种土方量方法进行介绍,然后结合实际中阜新市新邱区部分区域的土方量计算,按照技术要求,从外业数据采集和内业数据处理方面着手,运用方格网法和断面法对土方量计算方法进行分析,并提出了一些自己的观点。本文从实际出发,针对辽宁省阜新市彰武县部分乡镇的宅基地测量工作撰写了符合当地条件以及测量规程的宅基地测绘技术设计书,并且应用与实施。

Analysis and Application of Earthwork Calculation Methods

In order to ensure the economic efficiency of the project and allow the project to maximize its profitability in meeting the requirements,the accuracy of earthwork volume calculation is directly related to the economic benefits such as project investment and budget.Therefore,the amount of earthwork is critical for the project.In order to better meet the requirements of engineering projects and improve the accuracy of earthwork volume calculations,it is necessary to study and compare earthwork volume calculation methods to achieve the best solution.Common earthwork calculation methods are grid method,section method,contour method,and DTM method.According to the technical requirements,this paper introduces these four methods of earthwork calculation,and discusses the calculation of the amount of earthwork in some areas of Xinqiu district of Fuxin city field data collection and indoor data processing by using the grid method.The section method is used to analyze the method of earthwork volume calculation and propose some opinions.Based on practice,this paper applies and implements a technical specification of homestead surveying and mapping for some towns in Zhangwu county,which considers the local conditions and standard for surveying and mapping.
