【摘要】：穆陵關隧道屬于單向三車道公路隧道,是青州至臨沭高速公路關鍵控制性工程,埋深最大為40米,最小為5米,為典型的淺埋大跨度公路隧道。隧道工程地質條件復雜,下穿有2000多年歷史的齊長城遺址,隧址區(qū)地貌為典型的沖蝕溝“雞爪形”,圍巖以強風化花崗巖為主。基于復雜的工程條件,隧道施工過程中圍巖安全控制尤為重要,本文結合隧道地質超前預報和監(jiān)控量測,基于現(xiàn)場管理體制,構建了隧道施工過程中圍巖安全控制的管理體系,主要研究內容如下：(1)根據(jù)穆陵關隧道工程地質和隧道施工特性,考慮地表齊長城遺址的保護,確定了穆陵關隧道地表沉降控制標準。(2)根據(jù)隧道圍巖穩(wěn)定性影響因素,提出隧道工程安全控制相關措施。(3)為確保了隧道施工安全；采用現(xiàn)場監(jiān)控量測,及時調整施工措施,齊長城遺址施工段最大地表沉降控制在標準范圍以內,保證了歷史文物的安全。(4)針對近些年出現(xiàn)的隧道工程事故,對隧道工程事故進行了分類,結合隧道工程施工特點、隧道工程管理事故原因以及目前存在的施工管理體系問題,通過穆陵關隧道的管理實踐,建立了隧道工程安全控制管理體系。
[Abstract]:Mulingguan Tunnel is a one-way three-lane highway tunnel. It is a key control project of Qingzhou-Linshu Expressway. The maximum buried depth is 40 meters and the minimum is 5 meters. It is a typical shallow buried large-span highway tunnel. The geological conditions of tunnel engineering are complicated, and the site of Qithe Great Wall, which has a history of more than 2000 years, is located in the tunnel area. The geomorphology of the tunnel area is typical erosion ditch "Jijiao", and the surrounding rock is dominated by strongly weathered granite. Based on the complex engineering conditions, the safety control of surrounding rock in tunnel construction process is particularly important. This paper combines the tunnel geological forecast and monitoring measurement, based on the field management system, constructs the safety control management system of surrounding rock in the course of tunnel construction. The main research contents are as follows: (1) according to the engineering geology and tunnel construction characteristics of Mulingguan Tunnel, considering the protection of the site of the Great Wall, the control standard of surface subsidence of Mulingguan Tunnel is determined. (2) according to the influence factors of surrounding rock stability of the tunnel, In order to ensure the safety of tunnel construction, to adopt on-site monitoring and measurement and adjust construction measures in time, the maximum surface subsidence of the construction section of the Great Wall site is controlled within the standard range. The safety of historical relics is ensured. (4) in view of the tunnel engineering accidents in recent years, the tunnel engineering accidents are classified, combined with the characteristics of tunnel construction, the causes of tunnel engineering management accidents and the problems existing in the current construction management system. Through the management practice of Mulingguan tunnel, the safety control management system of tunnel engineering is established.
