Description
技术领域technical field
本发明涉及一种复杂地质环境条件下隧洞隧道围岩加固方法，尤其涉及一种围岩松动或软岩大变形的隧道加固控制方法。The invention relates to a method for strengthening the surrounding rock of a tunnel under complex geological environment conditions, in particular to a method for controlling the reinforcement of the surrounding rock for loose surrounding rock or large deformation of soft rock.
背景技术Background technique
当前我国隧道工程多用新奥法施工，其施工要点是在隧道开挖后尽快施做柔性的喷锚支护，使得支护结构与围岩共同产生适量变形以充分发挥围岩自稳定能力，二衬在合适时机再进行施做。如在地质复杂多变的地层进行隧道施工，往往由于前期勘察不够精细化导致设计施工考虑不周、施工不到位或由于外界不可控扰动因素如临近工程爆破施工，暴雨、台风及地震自然力等因素导致已成初支段围岩松动、恶化产生大变形。在这种工况下，如在没采取充分保护措施的情况下进行注浆加固施工，极可能由于围岩受到进一步扰动，在注浆体未充分硬化前便引起洞内收敛变形过大或拱顶下沉，甚至酿成塌方事故，对洞内作业人员及结构安全造成严重威胁。如是浅埋段从地表进行注浆加固，也极易导致隧道上方地表开裂，甚至出现山体滑坡现象；洞内也可能出现坍落而影响结构稳定性。如何安全有效地对恶化围岩进行二次加固，提升加固质量，对于当前隧道施工具有非常重要的现实意义。At present, the new Austrian method is mostly used in the construction of tunnel projects in our country. The key point of the construction is to implement flexible spray-bolt support as soon as possible after the excavation of the tunnel, so that the support structure and the surrounding rock can produce an appropriate amount of deformation to give full play to the self-stabilizing ability of the surrounding rock. The lining will be applied at the right time. For example, tunnel construction in geologically complex and changeable strata is often due to insufficient preliminary investigation, resulting in poor consideration of design and construction, inadequate construction, or due to external uncontrollable disturbance factors such as blasting construction of adjacent projects, heavy rain, typhoon and natural earthquake forces, etc. As a result, the surrounding rocks in the primary branch segment became loose and deteriorated, resulting in large deformation. Under such working conditions, if the grouting reinforcement construction is carried out without adequate protection measures, it is very likely that the surrounding rock will be further disturbed, causing excessive convergence deformation or arching in the cave before the grouting body is fully hardened. The roof sinks and even leads to a landslide accident, which poses a serious threat to the safety of workers and structures in the cave. If the shallow buried section is reinforced by grouting from the surface, it will easily lead to cracks on the surface above the tunnel, and even landslides; the cave may also collapse and affect the structural stability. How to safely and effectively carry out secondary reinforcement of deteriorated surrounding rock and improve the quality of reinforcement has very important practical significance for current tunnel construction.
