在大规模土方工程中,一般要在作业过程中同时进行挖掘、运输、填土和压实。为对这些大型土方工程施工进行有效管理,必须结合大型设备的作业进度和工程的特点及时分析和调整作业方式。为提高施工及管理效率及其准确度,将GPS及三维CAD等信息化施工技术组合而成的土方施工管理系统应运而生.该系统整体结构如图1所示。 In large-scale earthworks, excavation, transportation, filling and compaction are generally carried out simultaneously during the operation. In order to effectively manage the construction of these large-scale earthworks, it is necessary to timely analyze and adjust the methods of operation according to the operation schedule of large-scale equipment and the characteristics of the project. In order to improve the efficiency of construction and management and its accuracy, the construction management system of earthwork, which is a combination of GPS, 3D CAD and other information technology, came into being. The overall structure of the system is shown in Fig.1.
