| Abstract: | The interaction mechanisms of the composite supporting system of soil nail and row pile with strut were studied by theoretical research approach. According to the working principles of the row pile with strut supporting system and the soil nail supporting system, the restraint function of the row pile with strut to adjacent soil nail wall lateral deformation was analyzed. Combined with the deformation development characteristics of the soil nail wall during pit excavation, soil spaceing effect in the soil nail region were discussed. Moreover, the load and deformation in the supporting region of row pile with strut were also studied. These will laid a certain theoretical basis for design calculation and engineering application of this new composite supporting system. |
