摘　　要：车行地道结构由于尺寸较大,往往选用抗浮能力更强的抗浮桩作为抗浮工程措施。然而,对于工程地质较好的地区,抗浮锚杆的经济性效果更佳,且施工更为便捷。现对六安市某河道两侧的车行地道进行抗浮设计。由于河道两侧地质条件不同,针对不同的地质条件,对抗浮工程措施进行对比分析,选择经济合理的抗浮工程措施。通过计算分析得出,在岩石地质情况的河道北岸地道,抗浮锚杆更为经济合理;在砂层地质情况的河道南岸地道,抗浮桩更为经济合理。Due to the large size of the vehicle underpass,the anti-floating pile with stronger anti floating capacity is often selected as the anti-floating engineering measures.However,for areas with good engineering geology,the economic effect of anti-floating anchor is better,and the construction is more convenient.In this paper,the anti-floating design of the vehicle underpass on both sides of a river in Lv'an City is carried out.Due to the different geological conditions on both sides of the river,the anti-floating engineering measures for different geological conditions are compared and analyzed,and the economic and reasonable anti-floating engineering measures are selected.Through calculation and analysis,it is concluded that in the vehicle underpass on the North Bank of the river with rock geological conditions,the anti-floating anchor is more economical and reasonable;In the vehicle underpass on the South Bank of the river with soil geological conditions,the anti-floating pile is more economical and reasonable.
