摘要
由于隧道施工的复杂性、危险性,加强施工过程的风险和安全防范,采取正确和有力的安全措施和工艺,避免隧道施工过程中发生安全事故,造成人员伤害和设备损坏。地质超前预报的方法众多,都是以地震的反射和散射为理论基础,随着不同检测设备的出现以及应用,普遍存在技术缺陷,存在误报和预报位置不准确的风险,造成不可控制的灾害和事故,要达到地质超前预报的准确、客观,必须拥有科学的理论基础,可靠的数据处理系统,合理的检测技术流程,本文通过对TST系统进行客观的技术评价和合理分析,以及在曾家湾隧道施工中的应用,促进隧道超前预报的良好发展,推广TST方法在隧道超前预报中的广泛应用。
Because of the complexity and danger of tunnel construction, the risk and safety precautions in the construction process should be strengthened. Correct and effective safety measures and techniques should be adopted to avoid safety accidents and personnel injury and equipment damage during tunnel construction. There are many methods of geological advance prediction, which are based on the theory of reflection and scattering of earthquakes. With the emergence and application of different detection equipments, there are widespread technical defects, risks of misreporting and inaccurate location of prediction, resulting in uncontrollable disasters and accidents, so as to achieve the accuracy and objectivity of geological advance prediction. It is necessary to have scientific theoretical basis, reliable data processing system and reasonable detection technology process. This paper makes objective technical evaluation and reasonable analysis of TST system and its application in Zengjiawan tunnel construction, so as to promote the good development of tunnel prediction and popularize the application of TST method in tunnel prediction. General application.
