摘要：

为提高矿山法地铁隧道支护结构病害检测与识别的准确性，采用基于时域有限差分的数值模拟方法，建立常见形状空洞、充水空洞、不同填充介质脱空以及钢格栅拱架、H型钢架下空洞模型，模拟探地雷达波在不同病害中的传播规律，并通过青岛地铁3号线探测实例验证。结果表明：空洞病害雷达反射波通常呈双曲线形状，反射信号强，但上三角形空洞图像与其他空洞图像有较大差异，表现为倾斜平行的同相轴特征；当空洞或脱空内部含水时，空洞或脱空下部出现明显反射波；钢结构雷达波反射强烈，会对钢结构下方病害探测产生干扰，在实际探测中，应将初期支护与二次衬砌分开探测。

Abstract:

The service life of Metro tunnel constructed by mining method would be affected by cracks and corrosion of and hollows behind support structure. In order to improve the detection and recognition accuracy of support structure disease of Metro tunnel constructed by mining method, models of common shaped hollows, hollows contained with water, support structure gaps filled with different dielectrics and hollows behind steel grating arch and Hshaped steel arch are established by finitedifference timedomain method(FDTD). The propagation rules of ground penetrating radar wave in tunnel support structure are analyzed; the reflected results of different support structure diseases are analyzed; and a case study is made on engineering detection of Line No. 3 of Qingdao Metro. The results show that: 1) The radar reflection waves of hollows usually show as hyperbolic curves and their signals are strong. The radar images of triangle hollows which show as parallel inclined lineup are greatly different from those of other shaped hollows. 2) When the hollows and support structure gaps contained with water, the radar reflection waves are clearly visible at bottom of hollows and support structure gaps. 3) The steel structures of support structure have great influence on the detection and recognition of tunnel structure diseases; as a result, the diseases detection of primary support and secondary lining should be carried out respectively.

Key words: tunnel constructed by mining method, tunnel support structure disease, ground penetrating radar, finitedifference timedomain method, forward modeling
