| Abstract: | The foundation pit excavation in narrow site is very common in reconstruction and expansion of urban construction and industrial buildings. The safe and reliable support of excavation is necessary to ensure the safety of the surrounding buildings and the operation in the excavation. Micro steel pipe pile + anchor combined supporting system can effectively support the excavation. By 2 engineering cases, the paper described the combined supporting system about the design idea, specific design and the attentions in construction. |
