摘要
为了促进中国隧道检测与健康评价技术的发展,综述了隧道围岩及支护系统的病害检测与稳定性评估现状及发展,介绍了衬砌表观病害和结构内部缺陷的检测过程及方法,同时总结了最新的隧道健康状况评价方法。综合分析表明:在隧道检测方面,自动化的快速无损检测技术是隧道检测发展的重要方向,尤其是以图像自动识别、车载探地雷达、微震监测技术为代表的快速检测技术,在隧道不良地质段、钢拱锚喷联合支护及空洞病害探测中的应用越来越广泛;在隧道结构健康评价方面,结合断裂力学、分形理论和层次分析法等建立综合指标体系,为隧道支护结构的安全稳定性量化评价提供了可能。
In order to promote the development of tunnel inspection and health condition assessment in China,the current state and progress of disease detection and stability evaluation for surrounding rock and support system were reviewed.The inspection process and methods of apparent diseases and structural internal defects of tunnel lining were introduced,and the latest evaluation methods of tunnel structure health were summarized.The comprehensive analysis shows that the automated rapid nondestructive testing technology is an important development trend of tunnel inspection technology.The rapid inspection technologies,such as automatic image recognition,vehicle-mounted ground penetrating radar and microseismic monitoring technology,have become more and more widely used in tunnels with poor geological sections,combined steel arch and bolt-shotcrete support and cavity defects detection.As for the evaluation technology of tunnel structure health,fracture mechanics,fractal theory and analytic hierarchy process are used to establish a comprehensive index system,which provides the possibility for the quantitative evaluation of the safety and stability of tunnel support structure.
