格栅式地下连续墙的研究现状

Research Status of Lattice-Shaped Diaphragm Walls

自1979年首次应用于日本高铁桥梁基础以来,格栅式地下连续墙以其优良的工程特性引起了国内外学者的高度关注和重视。目前,格栅式地下连续墙在国内外大型桥梁基础中取得了较多的应用,并已逐步推广到水利、水电及船坞基坑工程的围护和防渗结构中。在调研国内外大量相关文献的基础上,分析了格栅式地下连续墙在桥梁基础中的应用及研究现状,其中重点阐述了国内外格栅式地下连续墙基础的试验、理论计算和数值模拟方面的研究进展,并进行了相关的总结和分析,以期对格栅式地下连续墙在土木工程中的进一步应用和研究方向提供一定的参考。

Since the first application case of the lattice-shaped diaphragm wall in Japanese high-speed rail bridges in 1979,it has attracted great attention from domestic and foreign scholars due to its excellent engineering characteristics.Currently,the lattice-shaped diaphragm wall has been used in large-scale bridge foundations at home and abroad and gradually popularized to the enclosure and anti-seepage structure of water conservancy,hydropower and dock foundation excavation engineering.Based on large amount of literature at home and abroad,the application and research status of lattice-shaped diaphragm walls in the bridge foundation was analyzed.The research progress of tests,theoretical calculations and numerical simulations of lattice-shaped diaphragm walls at home and abroad were focused on.Meanwhile,The relevant summary and analysis were implemented to provide certain guidance for the future application and research of lattice-shaped diaphragm walls in the civil engineering.
