Due to the disadvantages of current methods for monitoring and surveying foundation pits,such as low efficiency and slow feedback, this paper puts forward a new Web-based data management system. Through the application of the relational database model in actual projects, the data management system can perform a variety of functions. For instance,it can easily upload,access,export each of observational data,au-tomatically generate many kinds of data reports and analysis graphics,set an automatic alarm,and provide an important basis not only for the safety of foundation pit supports and the surrounding environment,but also for optimizing the construction parameters.%针对目前基坑监测数据处理效率低、反馈不及时等不足，从工程应用的角度出发，采用关系型数据库模型，设计开发了基于 Web 的数据管理系统，实现了方便上传、查阅、导出每一期观测数据，自动生成各种数据报表和分析图形，以及根据设定的报警值自动预警功能，为反映基坑支护结构及周边环境安全情况和优化施工参数提供了重要依据。
