主要介绍了PS测井技术的原理以及数据处理方法,该技术可为隧道工程的安全、快速掘进及不良地质的预测预报提供可靠的数据和准确的地质资料。通过对测试数据的统计分析,为划分围岩级别、勘察断裂构造提供信息,使得支护结构设计参数与隧道围岩级别更加匹配,断裂构造的位置、特征更加明确,保证隧道施工能高效、优质地完成。
This paper mainly introduces the principle and data processing method of PS logging technology, which can provide reliable data and accurate geological data for the safety of tunneling projects, rapid excavation and forecasting of unfavorable geology. Through the statistical analysis of the test data, it can provide information for division of surrounding rock level and investigation of fault structure, so that the design parameters of supporting structure are more matched with the surrounding rock of tunnel, the position and characteristics of fault structure are more clear, and the tunnel construction can be ensured to be efficient and of good quality Complete.
