In the past few years, Prof. Wu was the principal investigator or collaborator of more than 100 research projects sponsored by government or enterprises, including the National Natural Science Foundation of China, the Doctoral Fund of the Ministry of Education, the projects of the excellent youthful teacher of Ministry of Education and so on.

       Research interests: (1) Research on the working mechanism and new design method of steel lined reinforced concrete pipe and bifurcation of hydropower station. Steel-lined reinforced concrete structure of the hydropower station is a new type of structure of which part of the steel plate is instead of the steel bar, thus greatly reducing the technical difficulty of thick steel plate welding, saving the project investment and improving the structure safety. (2) Study on the structure of underground penstock and bifurcation. In order to solve the technical problems in the design and construction of high pressure pipeline of conventional underground hydropower stations and pumped storage plants, this study aims at putting forward a reasonable underground high pressure pipe and lining structure type for the large HD pipe system. (3) Research on the spiral case and powerhouse structure of large hydropower station. With the increasing capacity of hydroelectric generating set, the spiral case size and its internal water pressure are becoming bigger and bigger, resulting in thicker steel plate of spiral case which induces the difficulties in the processing of spiral case and the bloated investment. This study is mainly aimed at the spiral case embedding type of hydraulic turbine, the dynamic and static characteristics of the hydropower plant structure. (4) Computer aided design of hydropower station. This study mainly includes shape optimization, structure calculation, pipe expansion and engineering quantity calculation of all kinds of steel bifurcated pipe, also including the reinforcement calculation and ancillary mapping of the reinforced concrete structure (such as the intake of hydropower station, concrete bifurcation, spiral case, draft tube, etc.). The main purpose is to improve the efficiency of design work and reduce costs by using the high and new technology of computer aided design. (5) Stability analysis of surrounding rock and supporting structure of underground engineering. With the increasing scale of underground engineerings, the working states of these underground engineerings during the construction, operation and maintenance need to be simulated and analyzed. The simulation analysis focuses on the stability of surrounding rock and supporting structure optimization so as to speed up the construction progress and save the investment of the project.
