摘要
沉管隧道岸上段与水中段施工衔接多采用围堰方式实施,双排钢板桩围堰具有受力性能较好、止水可靠、能承受较大的变形及施工效率高等优点,因而受到广泛应用。但目前在计算方面多采用以经验为主的计算设计方法,结合实际工程就经典土压力法和有限元法对双排钢板桩围堰的受力稳定性进行一些分析对比,并提出适用建议,以供类似工程参考。
Cofferdam is often used to connect the upper bank section of immersed tunnel with the water section,double-row steel sheet pile cofferdam has reliable sealing force,withstand greater deformation and construction efficiency,it is widely used by engineering.But most of the calculation methods are based on experience.Combined with the actual engineering,the classical soil pressure method and the finite element method are used to analyze and compare the stress stability of the double-row steel sheet pile cofferdam,and put forward some applicable suggestions for similar engineering reference.
