基于机场跑道道面结构完整性的盾构施工控制

根据盾构穿越机场飞行区地基的沉降变形规律和保证道面结构完整性的条件下,令道面结构与地基保持相互接触、共同协调变形,推导了盾构穿越机场飞行区所允许的最大沉降量δmax公式.根据此公式可建立机场道面安全承受标准,进而对盾构施工等主要参数进行有效控制,保证工程安全顺利进行.

Shield Construction Control Based on Integrity of Pavement Structure of Airport Runway

More and more tunnels extension or new tunnels is through the areas which are sensitive to settlements as parking apron, flight zone et al. According to the law of foundation settlement while the shield through the flight zone, based on the precondition ensuring the integrity of pavement structure and that the pavement structure and foundation to maintain contact and co-deformation, the formula of maxim permission settlement is derived while shield through the flight zone. By the formula of , the safety standards for airport pavement structure can be established, and can control shield construction parameters effectively to ensure the engineers safety.
