Field monitoring and stability analysis of underground crude oil storage caverns in construction phase

  • 摘要: 现场监控量测是确保大型地下工程建造和运营安全的重要手段。地下水封石油洞库在中国刚刚起步,不但缺少监测方案设计原则、实施方法等方面的规范标准,还缺少对相关监测数据分析方面的研究。以国内首个正在实施的大型地下水封石油洞库建设项目为依托,首先介绍了适用于大型地下水封石油洞库的监测原则与实施方法,该原则和方法充分考虑工程特征、地质情况和经济适用性;其次介绍了洞库监测结果:洞室大部分监测断面的洞周围岩收敛变形、拱顶沉降、内部位移和围岩松动圈分别处于4~8 mm、3~6 mm、4~8 mm和0.9~1.8 m区间范围内,锚杆应力和接触应力值大部分控制在50 MPa和0.5 MPa以内;而后分析了监测数据:①黄岛地下水封石油洞库围岩变形和支护受力较小、岩体稳定性良好、设计支护方案合理;②综合全面的监控量测结果可准确地反映地下水封石油洞库稳定性特征;③监测数据显示地下水封石油洞库稳定性表现出显著的时空演化特征。该研究可为中国地下水封石油洞库监测技术和稳定性评价研究提供重要依据。
    Abstract: Field monitoring is one of the important methods to ensure construction and operation safety of large underground facilities. The construction of underground crude oil storage caverns just commences in China. There are no standards of field monitoring and examples for data analysis. Based on the experience on the first crude oil storage caverns in China, the monitoring principles and implementation method of underground crude oil storage caverns are introduced by fully considering engineering features, geological conditions and economic applicability. The monitoring results show that surrounding rock convergence, crown settlement, internal displacement and surrounding rock loose circle of most monitoring sections are in the ranges of 4~8 mm, 3~6 mm, 4~8 mm, 0.9~1.8 m, respectively, and the anchor bar stress and contact stress are less than 50 MPa and 0.5 MPa, respectively. It is concluded that: (1) The deformation and support stress of the rock mass are low. Its stability is good and the design of support scheme is reasonable. (2) The monitoring results from a comprehensive scheme can reflect the overall stability of the underground crude oil storage cavern. (3) The stability has the characteristics of spatial and time evolution.
