For the structure stress condition, the dead load is born mainly by continuous rigid-frame, and the live load is born by both the arch rib and the main beam, the force separately bora by the arch rib and the main beam is influenced by the whole rigidity of beam and arch, and by areas of flexible hanger rod, the structure perforce is no longer same with the common beam and arch, and the inner force analysis progress is more complex to the common bridge system, especially, the multi-direction stress analysis to the combination area of pier、 arch and beam is very difficult, for such reasons, so it is very necessary and important to have stress performance analysis in the combination area of pier、 arch and beam.

从结构受力情况来看，梁体自重主要由连续刚构承受，活载由拱肋与主梁二者共同承受，各自承受力的大小受梁、拱相互整体刚度、柔性吊杆面积的大小影响，结构性能已不同于一般的拱与梁，结构内力分析的过程较一般桥梁体系较为复杂，特别是墩、拱、梁结合处的多向受力状况的分析难度更大，所以对该桥式结构，墩、拱、梁结合部的结构受力特性进行进一步地理论分析测验研究也就显得十分必要和迫切了。

Test results have shown that larger plastic volumetric strain as well as higher growth rate of pore water pressure would be generated in multi-directional shearing than in a single-directional one. Lower resistance of sand to liquefaction was also observed under the rotation of principal stress orientation.
