摘要
随着我国基础设施建设的大力发展,小净距隧道在我国高速公路建设过程中的占比越来越高。由于地质条件的原因,部分小净距隧道可能会穿越岩堆体,而影响其施工安全的风险因素繁多、关系模糊复杂、风险因子不确定性大,导致风险发生概率存在各种不确定性。针对穿越岩堆体的小净距隧道,提出一种基于熵权-正态云模型的小净距隧道施工风险评估模型,选取工程地质条件、隧道设计、外部因素和工程管控等4个方面的15个评估指标,并以某实际隧道工程为例,论证了该模型在小净距隧道施工风险定量评估中应用的可行性和独特优势。该研究对其他类似工程施工的风险评估有一定的借鉴意义。
With the development of infrastructure construction in our country, more and more small clear distance tunnels have been constructed in the highway.Meanwhile, due to the geological conditions, some small clear distance tunnels may pass through the loose deposits, and there are many risk factors that affect the construction safety, with fuzzy and complex relationships and high ancertainly in risk factors resulting in various uncertainties in the probability of risk occurrence.For small clear distance tunnels through rock piles, a risk assessment model based on entropy weight-normal cloud model was proposed for the construction of small clear distance tunnels.Fifteen evaluation indexes from four aspects, including engineering geological conditions, tunnel design, external factors and engineering control, are selected.Taking an actual tunnel project as an example, the feasibility and unique advantages of the application of the model in the quantitative assessment of the construction risk of small clear distance tunnels are demonstrated, which is of some reference significance for the construction risk assessment of other similar projects.
