摘要

摘要: 岩溶地区盾构掘进过程中,复杂地质环境对隧道掌子面稳定性产生较大影响,进而引发开挖面失稳等安全问题。为准确评价掌子面稳定性,降低施工风险,提出一种基于云模型和D-S证据理论的安全评价方法,考虑影响因素的复杂性,解决评价信息的模糊不确定性及高冲突问题。根据大量工程实践和文献研究,从岩溶、施工以及围岩影响三个方面建立一套掌子面稳定性评价体系和标准。以云模型获取评价指标对于风险等级的关联度,继而转化为基本概率分配,利用D-S证据理论对多源证据信息进行融合和更新,实现掌子面安全风险实时评价,并基于全局敏感度确定敏感性因素。实例应用结果表明:评价段掌子面稳定性等级为Ⅱ级,能够保持相对稳定,与实际施工情况相符。

Abstract: During tunnelling with tunnel boring machines in karst, the complex geological environment has a larger impact on the stability of working faces of tunnels, which would caused risks such as destabilization of working faces. To accurately evaluate the stability of working faces and reduce construction risks, a safety evaluation method based on the cloud model and the D-S evidence theory was proposed to consider the complexity of effect factors, which could solve the problem of fuzzy uncertainty and high conflict of evaluation information. Based on a large number of engineering practices and literature research, a set of stability evaluation systems and criteria for working faces was established from 3 aspects: karst, construction and the influence of surrounding rock. The cloud model was used to obtain the correlation degree of evaluation indexes for risk levels and then transformed into basic probability assignment, and the D-S evidence theory was used to fuse and update the multi-source evidence information to realize the real-time evaluation for safety risk of working faces and determine the sensitivity factors based on the global sensitivity. The results of the practical application indicated that the stability grade for working faces of the evaluated section was Ⅱ and could keep relative stability, that was consistent with the actual construction situation.
