【摘要】 TSP-203系统(Tunnel Seismic Prediction System)是针对复杂地质条件设置的隧道挖掘超前地质预报系统,目前广泛应用.该系统从数据采集、处理和成果评估高度智能化,采用该系统可以预报隧道工作面前方至少100m围岩地质体的性质、位置和规模,并可算出其岩石物理力学参数,为确定合理的支护参数提供依据,提高了隧道施工安全和质量.本文针对TSP-203系统的野外工程中遇到的精度和勘探成本问题,根据石油地震勘探的理论方法,考虑系统观测的激发和接收两大因素,提出系统数据采集的改进方法:1)在信号激发方面提出组和爆炸方法;2)在针对信号接受方面提出传感器新的安装改进方法.更多还原

【Abstract】 Accompanying with the construction of our country,the quantity and the difficulties of tunnel engineering are becoming more and more.There will be accident because of the ambiguous geologic information in front of the tunnel face.Tunnel Seismic Prediction System(TSP-203 system)is designed for these problems,which is excellent intelligence in data acquisition,processing and evaluation.This system can predict at least l00m in ahead of the tunnel face where the kinds,locations and sizes of geologic blocks,and evaluate rock mechanical parameters.For this reason,it can confirm the evidence for reasonable timbering parameters,and ensure the quality and safety in tunnel operations.In this text,improvement opinions on data acquisition were brought out based on the petroleum earthquake exploring for enhancing the precision in the actual operation of data acquisition outside.更多还原
