Effect Analysis of Reinforcing the Strong Expansive Rock (Soil) of High-speed Railway Subgrade with Pile-plate Structure |
| |
| Abstract: | The basement rock section underlying the subgrade of Guiyang—Nanning high-speed railway has strong expansibility. The non-buried pile-plate structure is adopted to solve the problems of swelling upwarp of expansive rock (soil) foundation after soaking in water and settlement under embankment load. The test results show that the maximum subsidence value of the sections is 2.96 mm and the maximum rising value is 4.03 mm within 432 days after construction, which fully meets the requirements of the code. |
