闸底板是整个闸身结构的一个主要部分。由于基础条件不同,它的型式也就不同。淮河下游工程中常用的有空心底板和实心底板二种型式,如(图1)。空心底板适宜于—般土壤较差的天然地基,这样在不影响底板刚度的情况下,可以减轻一部分基础的承载量,不致使基础破坏或发生过大的沉陷。实心底板常用于较好的天然地基,因为施工简单,采用较普遍。本文所谈的仅限于实心底板的应力分析问题。
The sluice floor is a major part of the entire sluice structure. Because of different basic conditions, its type is also different. Huaihe River projects commonly used in the hollow floor and solid floor of two types, such as (Figure 1). Hollow floor is suitable for natural soils with poor soil quality, so that it can reduce the bearing capacity of a part of the foundation without affecting the stiffness of the floor without damaging the foundation or causing excessive settlement. Solid floor commonly used for better natural foundation, because the construction is simple, more common. This article is limited to solid floor stress analysis.
