| 摘 要： | 厦门翔安海底隧道是我国第一条海底隧道,陆域浅埋暗挖地段,其地质条件差,多为全、强风化花岗岩,且地下水丰富.前期施工过程中支护结构常发生较大的变形,为了保证施工安全和进度,通过现场试验,得出一套合理的控制变形措施,使隧道拱顶下沉、水平收敛得到较好控制.在海底硬岩地段进行了钻爆试验,得出较好的爆破方案和参数,并采用声波仪和位移计对围岩损伤范围进行了检测.

| Abstract: | Xiamen Xiang'an subsea tunnel is the first subsea tunnel in China,whose geological conditions in the land are strongly weathered granite with enriched groundwater,shallow-buried excavation method is adopted.During the tunnel construction,the deformation of tunnel support is great.It is important to seek for a reasonable countermeasure to restrict the large deformation to ensure safety construction and advance through trials in locale.The arch crown settlement and level convergence are controlled effectively... |
