| Abstract: | The foundation of invert siphon project on Beiru river was on the clay rock layer which was 18-m deep underground. The irregular fractures caused ineffective drainage and slow down the construction process. The paper introduced the foundation replacement which was applied into the invert siphon project and solved the problem, for reference. |
