一、引言建造在岩石或土壤地基上的船闸是由闸墙(墩)组成的 U 形结构物,墙后有土体回填,运转时闸室墙前迎水。因此,船闸建筑物的动力特性,决定于墙体结构、水体、回填土体和地基的共同作用。目前工程设计中,仅以闸墙(墩)结构的动力特性作为分析的依据,而忽略土体、水体和地基的影响,显然是不合理的。 I. INTRODUCTION The ship lock built on the rock or soil foundation is a U-shaped structure composed of sluice walls (piers). The back of the wall is backfilled with soil, and the sluice wall is flooded before operation. Therefore, the dynamic characteristics of the lock building are determined by the combined effects of wall structure, water body, backfill soil and foundation. In the current engineering design, only the dynamic characteristics of the sluice wall (pier) structure are taken as the basis for analysis. It is obviously unreasonable to ignore the effects of soil, water and foundation.
