岩溶地区超前地质预报方法对比分析
|
摘要
在岩溶地区修建隧道时,由于地下岩溶发育的复杂性和多变性,经常会发生突水、突泥等地质灾害,给施工带来很大的经济损失,很多情况下还造成地表水源枯竭、环境污染等问题。目前,防止灾害发生的有效措施是提高超前地质预报在岩溶隧道预报中的精度,及时采取相应的预防措施。首先,总结了超前地质预报的主要内容。然后,针对棋盘式#3横洞开挖过程中出现的一次大涌水,通过现场地质调查,分析了开挖前方溶腔的类型和特征。运用TSP-203探测仪器、GPR、水平地质钻机对前方溶腔的位置和规模进行了探测。在综合地质预报的基础上将掌子面前方的溶腔挖开,将挖开后的实际情况与地质预报结果进行了对比,对二者相符合的部分进行了总结,不符部分的原因进行了分析,对存在的问题进行了探讨。研究旨在提高岩溶地区超前地质预报的精度,最大程度地减少地质灾害造成的人员伤亡和财产损失。
According to the complexity and changeability of the tunnels construction in karst aeras,geological disasters such as water flush and mud rush often occur during construction of tunnels,which bring much economic loss to construction,mostly also bring surface water to exhaustion and pollute environment,etc.At present,the effective measure to prevent disaster occurrence is improving the accuracy of the geological prediction in karst tunnels and taking the corresponding preventive measures promptly.First,the primary content of geological prediction is summarized.Then,as for the water flush in the process of excavating Qipanshi #3 cross tunnel,the characteristics and types of caves in front of the face are analyzed based on the geological investigation,the location and size of the caves in front of the face are speculated by TSP-203,GPR and horizontal geological drilling machine,and the caves in front of the face are excavated based on the results of geological prediction.The actual situation after excavation and the geological prediction results are compared,the consistent parts of them are summarized,the reasons of the inconsistent parts are analyzed,and the existing problems are discussed.The purpose of the research is to improve the accuracy of the geological prediction and to reduce the investment and casualties of the project to the best extent in construction of karst tunnels.
