为研究不同结构参数下斜交板拱的受力特性，建立不同斜交角度、矢跨比的空间斜交板拱有限元模型，对其结构响应进行对比分析。结果表明：随着斜交角度的增大，拱脚反力极不均匀，板拱的扭转和翘曲效应越来越明显；矢跨比变化时，斜度对斜板拱的受力特性影响规律相同，但结构空间受力特性的强度明显不同。

To study spatial stress characteristics of skew arch in different structure parameters,skew arch finite models with different oblique angles and different span ratios are built,and the structure responses are compared and analyzed.The results show that arch foot reaction force is extremely uneven and the twisting and warping effects of skew arch are increasingly evident as the oblique angle increases when the span ratio is changed,the effect law of oblique angle on skew arch remains unchanged,but the strength of spatial stress characteristic is apparently different.
