【摘要】 随着社会经济的快速发展，一些大型的高速铁路、公路及城市轨道交通等正在大规模地兴建和规划当中，大型隧道也越来越多，其中对于隧道施工安全和进度的控制是整个工程的关键。为了避免盲目施工带来的突泥、突水、塌方等一系列安全事故、减少经济损失和提高隧道施工效率，隧道在开挖前必须准确的了解掌子面前面不良地质情况，因此隧道工程师们研究了很对隧道地质超前预报方法。其中TSP（TunnelSeismicPrediction）地震反射波法是以地震反射波理论为基础，具有适用范围广、预报距离长、对隧道施工干扰小、探测时间短、无明显场地限制、节约投资费用、提交资料及时等诸多优点，因此在国内外得到了广泛的应用。但是目前TSP地震反射波法在隧道施工超前地质预报中还存在很多问题，主要是受到环境、操作和数据分析等原因影响，预报结果有一定的误差。目前关于预报准确性方面研究甚少，这不利于TSP的推广和应用。TSP隧道超前地质预报的准确性所涉及的因素很多，所以要综合考虑其影响因素对其进行评判。主要研究内容如下：⑴阐述了TSP预报系统的应用原理，针对天平铁路（甘肃天水至平凉）六盘山隧道复杂的地质条件，对其应用效果进行了实例分析，在此基础上对已做工程进行了统计分析。⑵引入模糊数学的相关理论，综合分析了TSP预报准确性的影响因素，建立了评判其准确性的四层次模型。⑶采用专家调查问卷的形式，确定了TSP预报中各种影响因素评价指标的相对权重。⑷通过准确性评判模型在六盘山隧道TSP预报实例中的运用，对其评判结果与实际情况进行了对比分析，验证了模型的合理性。更多还原

【Abstract】 With the rapid development of social economy, A number of large high-speed railway、highway and urban rail transit projects are being large-scale constructed and planning, meanwhile, more and more large tunnel, while, The tunnel construction safety and progress control is the key to project. In order to avoid blind construction brings sudden mud, water inrush, collapse and a series of accidents, reduce the economic losses and improve the efficiency of tunnel construction, Must be to accurate understanding of the adverse geological situation of the front of face conditions before tunnel excavation. Therefore, there are many tunnel geological prediction methods by study. Such as the TSP, having advantages-wide range, long forecast distance, small interference in tunneling, short detection time, no significant site constraints, investment costs saved, timely information submitted, and so on, is widely applied in at home and abroad.But, at present, there are some problems about the TSP seismic reflection wave method, mainly affected by environment, operations and data analysis, correspondingly, forecast results have a certain error. Little study is done on forecast accuracy, which is not conducive to the promotion and application of TSP. Many factors are involved in accuracy of the tunnel geological prediction accuracy, so comprehensive consideration of factors is to be judged. Specific activities include the followings:(1) Describes the application principle of the TSP prediction system and for the balance rail (Tianshui of Gansu to Pingliang of Gansu)the Liupanshan tunnel complex geological conditions, the application effect example, and the done projects’ statistical analysis is on the basis of above.(2) The introduction of the theory of fuzzy mathematics, comprehensive analysis of the TSP prediction accuracy factors and the establishment of a four-level model to judge their accuracy.(3) In the form of expert questionnaire to determine the relative weight of the TSP prediction in a variety of factors evaluation.(4) Accuracy evaluation model used in the TSP tunnel geological prediction instance of the Liupanshan, a comparative analysis of their evaluation results with the actual situation and verifies that the model is reasonable.更多还原
