摘要
对于地下工程,特别是隧道工程,遭遇复杂多变的地质情况不可避免,而针对地质情况选择合适的施工方法,使工程能够顺利完成则是我们的目标。在大铲岛—孖州岛过海隧道工程的设计中,平面上采用直线设计形式;纵断面设计考虑了航道部门的要求,以及隧道围岩具体的地质情况,采用"一"字单坡的形式进行设计。针对隧道两端地质好、中间地质差的特点,分别采用了矿山法和盾构法相结合的复合施工方法,由于技术方案得当,使整个工程在计划工期内得以顺利完成。
In the design of subsea tunnel between Mazhou island and Dachan island, straight alignment was adopted in plan design and single slopes were adopted in profile design, considering the navigation requirements and the geological condition of surrounding rocks. Mining excavation and shield driving were adopted respectively accounting for the situation that geologic conditions are good on both end sections and bad on the middle section. Thanks to the proper technical arrangements, the project has been smoothly accomplished on schedule.
