【摘要】 在南水北调一期工程中,郑州1段第二标段地质条件复杂,岩石的强度、埋深不一,需要对不同强度岩石的开挖方量进行计算,对应采取不同的开挖方案。分别采用断面计算法、不规则三角网法、方格网计算法等方法对基岩的空间分布、开挖方量计算进行了详细的研究,为渠道开挖施工提供必要的科学参数,为科学信息化施工组织提供技术支撑。更多还原

【Abstract】 In the first stage of the South-to-north Water Transfer Project,the geological conditions of the second section of the one section of Zhengzhou and the types of foundation soil of the canal are complex.There are a series of problems during the excavation process,such as the different strength of the same rock,especially the undulating boundary of the rocks and the different buried depth.In order to calculate the excavation volume of the rocks with different strength,we should take the corresponding approaches to the problems.This article made a detail research on the spatial distribution of the basic rocks and the calculation for the volume of the excavation and used the cross,vertical method to provide the necessary technology data in this project and provided a technology support for planning and programming of project construction.更多还原
