公路隧道施工过程中遇到水平产状的岩层时处理不当极易出现围岩失稳、坍塌等事故，这些事故将对隧道施工人员、设备安全造成不利影响。以石塘隧道为工程背景，分析该隧道地表沉降、拱顶下沉及周边收敛、围岩内部位移、锚杆轴力、围岩与初期支护间压力监控量测结果，研究其变化规律。研究结果用以指导该隧道后续施工和设计方案优化，并可为类似水平岩层隧道设计、施工及监测提供借鉴。
公路隧道施工過程中遇到水平產狀的巖層時處理不噹極易齣現圍巖失穩、坍塌等事故，這些事故將對隧道施工人員、設備安全造成不利影響。以石塘隧道為工程揹景，分析該隧道地錶沉降、拱頂下沉及週邊收斂、圍巖內部位移、錨桿軸力、圍巖與初期支護間壓力鑑控量測結果，研究其變化規律。研究結果用以指導該隧道後續施工和設計方案優化，併可為類似水平巖層隧道設計、施工及鑑測提供藉鑒。

During the construction of highway tunnel in horizontal rock layers, if proper measures are not taken, some accidents such as instability and collapse of surrounding rock may happen. These accidents may cause dangerous effects on the safety of workers and equipments in the tunnel. Taking the construc- tion of Shitang tunnel as the case, analysis is made on the monitoring and measurement results of ground settlement, crown settlement and convergence around the tunnel, the displacement of the interior of sur- rounding rock, bolt axial forces and pressure of surrounding rocks and preliminary support. The variation laws of these items are studied to provide the basis for modifying and optimizing the design and construc- tion schemes, which will offer some references for the design, construction and monitoring of tunnel in the similar geological conditions.
