综合物探技术在输水隧洞涌水突泥灾害探测中的应用
Application of comprehensive geophysical prospecting technology in water gushing and mud inrush disaster detection of water conveyance tunnel
摘要
Abstract
In this paper,the passive surface wave exploration method and TRT(True Reflection Tomography)advance geological prediction method are used to investigate the water gushing mud tunnel section of a tunnel in the central Yunnan water diversion project.Based on the fast,economical and efficient features of linear array,the extended spatial autocorrelation method is used to extract the surface wave dispersion curve from the fretting signal,inversely calculate the shear wave velocity and draw the profile,and analyze the abnormal form,and then combine the TRT advance geological prediction results to carry out refined interpretation.The spatial distribution of bad geological bodies,such as the accumulation area of water gushing mud and its influence area in front of the water conveyance tunnel were accurately detected.The results show that the combined application of the passive surface wave exploration method and the TRT advance geological prediction method in the water conveyance tunnel has a good effect on the detection of the scale and spatial distribution of the undesirable geological body in the tunnel,which provides a reliable basis for the subsequent engineering design and construction scheme selection.关键词
