水下大跨隧道小间距施工相互影响及应对措施研究

Interaction of Underwater Large Span Tunnels with Small Spacing and Solutions

随着我国公路事业突飞猛进的发展,小间距隧道大量涌现,由于小间距隧道施工受地质条件及地下空间的综合影响,因此对安全施工提出许多技术难题.依托实体工程对水下小间距隧道工程问题从理论基础、影响因素、影响程度、应对措施等方面进行了深入研究,施工中解决了许多技术难题,对今后类似工程的修建提供了大量的技术支持,从而使水下小间距隧道的施工技术得到快速的发展.

Along with the development of our country＇s expressway by leaps and bounds, small spacing tunnels emerge in a large number. As a result of the influence of geological condition and the underground space, many technical problems for the safe construction of the tunnels with small spacing come up. Taking on the entity project as an example, the theoretical basis, influence factors and influence degree,count er measures and so on are analyzed in detail. The engineering technical problems of underwater tunnels with small spacing are solved and a large number of technical supports for the construction of similar projects in the future are given,which can promate the rapid development of construction technoloy of the underwater small spacing tunnels.
