基于机场跑道道面结构完整性的盾构施工控制

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

摘要:

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.

Abstract:

In order to ensure the integrity of pavement structure, and to maintain the pavement structure and foundation to be in contact and in co deformation, the formula of the accepted maximum settlement δmax is derived according to the law of foundation settlement while the shield goes through the flight zone, therefore, the safety standards for airport pavement structure are proposed. As a result, the shield construction parameters can be controlled effectively to ensure the safety of the construction.
