摘要:
河道控导工程的基坑一般采用放坡的型式,当施工范围受征地拆迁限制时,常需要采用灌注排桩等基坑支护措施。苏南地区活动堰结构的设计常采用“弹性地基梁”法计算典型断面的弯矩,然后参照规范进行配筋,其中基坑的开挖方式会对活动堰结构内力产生显著的影响。通过数值模拟计算的方法,以太仓28 m大孔径活动堰为例,研究了不同基坑开挖方式下活动堰底板弯矩的变化。研究结果表明:灌注排桩支护可以有效减小底板的弯矩,且随着桩长的增加效果越明显。
Abstract:
The foundation pit of river course control and guide engineering generally adopts the type of slope placement. When the construction scope was limited by land requisition and removal, it's often necessary to adopt foundation pit support measures such as cast-in-place pile and so on. In the design of movable The elastic foundation beam method was often used to calculate the bending moment of the typical section in the design of the movable weir structure in southern Jiangsu, and then the reinforcement was carried out according to the specification. The excavation method of the foundation pit would have a significant impact on the internal force of movable weir structure. By means of numerical simulation and calculation, taking 28 m large aperture moving weir in Taicang as an example, the change of bending moment of movable weir bottom plate under different excavation methods was studied. The results showed that the cast-in-place pile support could effectively reduce the bending moment of the bottom plate, and the more obvious the effect was with the increase of pile length.
