提高TSP超前地质预报精度的方法研究
|
摘要
由于岩溶问题的复杂性、多变性和不确定性,地质预报准确率较低,这是国内外隧道施工地质界尚未攻克的技术难题。TSP(Tunnel Seismic Prediction)作为一项成熟的长距离超前预报技术,在预报软弱地层的分布、断层及其影响带和裂隙发育带等方面有许多成功的案例。简要介绍了TSP系统的原理及工作方法,并结合方都山隧道施工,从不同的方面研究如何提高TSP的探测精度。
Due to the complexity,changeability and uncertainty of karsts terrains,the rate of predicting accuracy is low.It is a technological problem which remains unsolved in the geological field of tunnel construction both at home and abroad.TSP predicting method is a kind of mature technology for long distance prediction.There are a lot of successful cases in our prediction of the distribution of the weak stratums and faults.In this article,the author briefly introduces the TSP principle and application method and studies from different aspects how to improve TSP detecting precision,and the research results have been applied to the construction of the Fangdushan Tunnel with favorable effects.
