2007年01月18日，中铁**局集团**铁路指挥部地质预测预报中心对***隧道出口正洞DK126+906～DK126+756范围内地质情况进行了探测。本次探测采用TSP 203仪器进行资料采集。激发20炮，炮点距1.5m，一个接收器置于隧道左边墙DK127+120处接收，采集参数为：采样率62.5μs，记录长度7218样点，X-Y-Z三分量接收。采集时炮眼深度1.5米，采用膨胀剂堵塞。接收器深度为2米，套筒与岩石耦合状况良好，系统工作正常。

January 18, 2007, China Railway Group ** ** Board Railway headquarters Geological Forecasting Center *** Tunnel are holes DK126 +906 ~ DK126 +756 carried out within the scope of geological exploration. The detection equipment used for data collection TSP 203. Excitation of 20 guns, artillery dot pitch of 1.5m, a receiver placed in the tunnel on the left wall of DK127 +120 office reception, acquisition parameters were: sampling rate 62.5μs, record length of 7218 samples, XYZ three-component receivers. Collection depth of 1.5 meters when the borehole, blocked with expansive agent. Receiver depth of 2 meters, coupling sleeve and the rock is good, the system is working properly.
