| Abstract: | In this paper,the theory background and characteristic of 3-demensional fast Lagrangain method are introduced.A practical engineering example with excavation and soil nailing of a foundation pit is analyzed,the difference between numerical simulation results and practical measuring data is also discussed.Some useful conclusions are drawn.It also indicates that 3-dimensional fast Lagrangian method is a reliable and powerful tool for foundation engineering and this method should be widely used in geotechnical engineering in the future. |
| Keywords: | foundation pit soil nailing numerical simulation 3-dimensional fast Lagrangian method |
