| 摘 要： | 湛江湾隧道是国内首条采用盾构法施工的跨海隧道，施工及运营期间将承受海底60m水头压力。为了解隧道外侧真实荷载情况，该文创新了深水海底隧道管片外水土压力监测方法，成功有效监测到盾构管片外侧水土压力值。监测成果显示，深水软土盾构隧道外荷载仍以水压为主，水压分布符合静水压强分布规律，监测方法与成果对今后沿海深水软土盾构隧道的设计施工监测具有非常重要参考价值。

| Abstract: | Zhanjiang bay tunnel is the domestic first cross-sea tunnel construction by shield method , which will withstand a hydrau-lic pressure of 60m during the construction and operation .In order to understand the tunnel external real load condition , this article innovates the deep tunnel segment outer water and soil pressure monitoring method , which successful and effectivly monitors the lat-eral water and soil pressure value of shield segment .It is shown that , the deep soft soil shield tunnel external load is mainly focus on water pressure , and water pressure follows static water pressure distribution .Monitoring method and results for future deepwater coastal soft soil shield tunnel design and construction monitoring has very important reference value . |
