摘要
本文应用自行开发的岩石破坏过程分析软件F-RFPA2D对广州地铁二号线隧道施工引起海珠广场地表沉陷事故进行了数值模拟分析,再现了岩体塌陷破坏的全过程,阐明了沉陷事故的原因。
The accident of surface subsidence at Haizhu Square,Guangzhou caused by the construction of Guangzhou Subway No. 2 tunnel is analyzed by numerical simulation code,Flow-Rock Failure Process Analysis (F-RFPA2D),which is developed by the authers. The evolution process of rockmass failure and falling are obtained by the numerical simulation. The numerical simulation is helpful to explain the cause of the surface subsidence accident and find the correct measure to control the further failure and falling.
