Study on Influence of Pit Width Effect on Bulge at Bottom of Pit

Wu Chuanbo  
The article analyzes the infuence of the pit width effect on the bulge at bottom of pit through the numerical simulation of bulge at the bottom of the pit with the different width depth ratio.The study opens out the rule of the bulge deformation at the bottom of the pit with the different width depth ratio,and makes clear that the maximum bulge level at the bottom of pit will continuously increase with the continuous increment of the pit width depth ratio.Combined with the engineering case analysis of Shanghai East-West Passage overpassing Metro No.2 Line,the article points out that the wide and large pit with the utmost high requirement of environmental protection can efficiently control the bulge at the bottom of pit by the mode of dividing the large pit into the small pit.
