摘要

摘要: 非对称连拱隧道具有几何与结构形式不对称、开挖跨度大、施工工序繁多、结构受力复杂等力学特性,在进行支护结构设计中通常需要进行荷载-结构模型验算,而其荷载确定尚无成熟的计算方法。在此背景下,考虑了左右两洞室几何与结构形式不对称条件,基于连拱隧道双塌落拱的基本假定,根据普氏理论推导了深埋情况的围岩压力计算公式。将推导公式取对称条件,则可以退化为常规连拱隧道的计算公式,验证了所推导公式的正确性。最后结合工程实例,验证了所推导公式的合理性。研究方法和结论可以为非对称连拱隧道的设计荷载确定提供重要参考。

Abstract: The mechanical characteristics of asymmetrical multi-arch tunnels are as follows: a symmetric geometry and structure form, large excavation span, various construction processes and complex structural stress. Therefore in the design of supporting structures, the load-structure model is usually used, and till now there aren't any mature methods for estimating the load. In this context, the conditions of asymmetric geometry and structure form of two cavities of a tunnel are considered. Based on the assumption of the double collapsed arches of multi-arch tunnels and according to the Protodyakonov's theory, a formula for calculating the rock pressure under deep buried conditions is derived. Under symmetrical conditions, the derived formula becomes the conventional formula for multi-arch tunnels, which has proved the validity of the derived formula. The research methods and conclusions may provide an important reference for the determination of the design load of asymmetrical multi-arch tunnels.
