随着高速公路隧道越来越多,隧道各方面的技术研究与应用也越来越得到人们的重视,经过近几年的摸索与研究,隧道暗洞的施工工艺及方法已经趋于成熟。但是由于岩层的不确定性以及其复杂的应力结构,在实际施工中原设计往往满足不了实际施工的需要,尤其是隧道洞口段,如果支护加固不到位,更存在着极大的安全隐患,本文将结合枫相3号隧道的实际情况,浅谈隧道洞口松散体加固技术。
With more and more expressway tunnels, more and more attention has been paid to the technical research and application of tunnels. Through the exploration and research in recent years, the construction techniques and methods of tunnel dark holes have become mature. However, due to the uncertainty of rock formation and its complicated stress structure, the original design often can not meet the actual construction needs in practical construction. Especially for the tunnel entrance section, there is a great potential safety hazard if the support reinforcement is not in place. Will be combined with the actual situation Maple No. 3 tunnel, tunnel bulkhead loose reinforcement technology.
