| 摘 要： | 以某高压输电线路为依托来研究中空式混凝土复合防护大板基础;分别建立中空式混凝土复合防护大板基础和普通混凝土防护大板基础的有限元模型,在土层水平运动(土层的水平拉伸、压缩)下对两种模型进行分析研究。得到中空大板和普通大板的应力变化规律和两种大板基础下输电铁塔的塔腿支座位移变化规律,并提出了中空式混凝土复合防护大板相对于普通混凝土复合防护大板基础的"相对位移"概念,从而较好的验证中空式混凝土复合防护大板的实用性。

| Abstract: | Hollow type concrete composite protective slab foundation was researched in this paper, which was based on a high voltage transmission line. The finite element model of Hollow type concrete composite protective slab foundation and ordinary oncrete composite protective slab foundation was established. The two models were analyzed in the soil horizontal movement (soil horizontal tensile and compression). The stress of the slab and displacement of the transmission tower pedestal were Got. The concept of "relative displacement" of hollow type concrete composite protective slab foundation was put forward, which compared with ordinary oncrete composite protective slab foundation, and validated the practicality of hollow type concrete composite protective slab foundation better. |
