| 摘 要： | FRP复合板桩弹性模量较低，在使用过程中易产生较大的变形而导致结构无法正常使用，因此设计时要考虑其变形特性。FRP复合板桩的变形包括弯曲变形和剪切变形两部分。通过一种简化的计算FRP板桩变形的方法，使FRP复合板桩设计更为方便。运用该法计算出的最大变形与有限元计算结果较为接近，表明该法具有一定的可靠性。

| Abstract: | Fiberglass-reinforced plastic (FRP) composite sheet pile has relative low elastic modulus and the shape of the thin-walled structure in which excessive deflection will occour. And this will effect its normal operation. The deflection of FRP sheet pile includes bending deflection and shear deflection. A simplified method is introduced to calculate the deflection of FRP sheet pile wall. The maximum deflection obtained from this method is very close to that from finite element method; and it is shown that the method proposed is quite reliable. |
