摘要
运营公路隧道仰拱病害严重影响隧道的整体稳定和长期运营安全,目前国内外对仰拱病害的形成机制和治理手段已有一定研究,但对仰拱缺陷的深入探讨的较少.文中以天定高速秦州隧道为工程背景,结合国内标准提出了运营公路隧道仰拱缺陷评定标准,基于秦州隧道仰拱病害检测结果对其成因进行了分析,并提出仰拱加固施工方案.整治效果良好,为优化设计和类似工程病害整治提供借鉴经验.
Abstract
The invert disease of operating highway tunnels seriously affects the overall stability and long-term opera-tional safety of the tunnel.At present,some research focus on the formation mechanism and treatment methods of arch diseases both domestically and internationally,but there is a lack of in-depth exploration of arch defects.Tak-ing the Qinzhou Tunnel of Tianding Expressway as the case,an evaluation standard for inverted arch defects in oper-ating highway tunnels is proposed based on domestic standards.According to the inspection results of inverted arch defects,the causes are analyzed,and an inverted arch reinforcement is proposed accordingly,which has a good ef-fect,providing the reference experience for optimizing design and similar engineering disease remediation.
