Abstract: As Internet + technologies develop, informatization, mobile office, and resources sharing have become the trends of various industries. In hydraulic engineering, geotechnical engineering, and engineering geology fields, most calculations are based on desktop software, which lacks standardized management and qualified teamwork performance, resulting in the waste of resources. Based on cloud computing technology, we made a detailed exploration from the technical aspects of algorithms, 2D and 3D visualization and interface interaction and hence developed a Web-oriented hydraulic cloud computing platform—THC. The cross-platform cloud computing and cloud visual, cloud approval, cloud sharing and etc. of the calculations can be completed using THC. The applications of THC's four major modules, namely, statistical analysis of rock mass, geotechnical test, slope stability analysis, and flood routing, demonstrate that THC provides reliable and convenient computing services for users. Meanwhile, as the first cloud computing platform with good interaction in the field of hydraulic and civil engineering, THC also offers sound computing services for teachers, students, enterprises and researchers, and is of great significance to promoting the standardization and information management of data.

Key words: hydraulic cloud computing platform (THC), engineering geology, cloud computing, information, software service
