随着能源和水资源的不断开发,水电工程的发电引水系统大多采用埋藏式地下洞群结构且处于高山峡谷的环境中。施工过程中时常受到高地应力的影响,安全风险较大。文章通过高低应力条件下地下交叉洞室开挖施工技术的应用,减小安全隐患,为类似在高地应力条件下地下交叉洞室开挖的设计、施工提供借鉴经验。 With the continuous development of energy and water resources, the power generation and water-diversion systems of hydropower projects mostly use buried underground caverns and are in the environment of alpine gorges. During the construction process, it is often affected by the stress of the high ground, so the safety risk is high. In this paper, through the application of the construction technology of underground cross caverns under the condition of high and low stress, the potential safety hazard is reduced, which provides reference for the design and construction of similar cross-caverns under high ground stress conditions.
