基于南方CASS软件的土方量计算方法

威海内海吹填工程主要施工内容是采用吹砂挤淤方式进行吹填，吹填区吹填完成后采用机械压实。在施工过程中须多次对吹填区进行进度测量，涉及土方量的计算频率较高。为保证工程土方量的计算准确，将南方CASS软件的不同土方量计算方法进行对比，并结合工程实际情况分析选择合理的计算方法，从而为工程质量和进度控制提供依据。结果表明，选择合适的计算方法不仅能够准确地计算土方量，还能形象地反映现场的实际情况。

Calculation method for earthwork volume based on software of South CASS

The main construction content of the reclamation project in Weihai inner sea is using the method of sand blasting and silt squeezing to hydraulic fill.Mechanical compaction should be adopted after the completion of hydraulic filling in reclamation area.In the process of construction,it is necessary to measure the progress of the reclamation area for many times,and the calculation frequency of earthwork volume is relatively high.In order to ensure the accuracy of earthwork volume calculation,we compare different earthwork volume calculation methods of South CASS software,and select the reasonable calculation methods based on the actual situation of the project,so as to provide basis for project quality and schedule control.The results show that selecting the appropriate calculation method can accurately calculate the earthwork volume,and reflect the actual situation of the site vividly.
