摘要
Abstract
Shenzhen Metro Line 3 passes through the Liberation Road section of Guangzhou - Shenzhen railway, underpinning should be carried out for the foundations of a continuous beam bridge and a continuous rigid frame bridge. The construction site features rich groundwater, limited space, poor geological conditions. Considering the difficulties of underpinning for the continuous beam bridge and continuous rigid pile bridge, the paper introduces the underpinning program, steps and treatment of the interaction of newly underpinned piles with overlapping tunnels, option for removing the old piles and construction monitoring requirements, and describes in-depth the auxiliary measures for underpinning and the major steps. The practice can be taken for reference by professional colleagues.关键词
