3通过对上述结构面的分析，得出其总体特征为：左坝肩以变玄武岩片理为主体，呈顺向结构，岩体内缓倾角节理极不发育；右坝肩主要为断裂及节理型结构面，呈反向结构，且具有明显的宏观板状结构特征，并发育有一定厚度的构造软岩带。

Since inextensible reinforcements do not stretch under design loading, they are the preferred MSE reinforcement type for highway structures in general and for critical structures such as bridge abutments in particular, where deformation control is crucial to structural performance of both the superstructure and the abutment.5 Inextensible reinforcements have been used successfully in MSE bridge abutment structures for thirty-five years, while research is still underway trying to develop an extensible

由于不可拉伸的加筋体在设计承载下不能拉伸变形，因此它们一般是公路结构，尤其是桥肩等重要结构中的首选材料，因为在这些结构中，变形控制对上层建筑和桥肩中性能表现是很关键的因素。不可拉伸加筋体在加筋土桥肩结构中已经成功的使用了35年，与此同时，研究能够在桥肩应用中性能有保证的可拉伸加筋体的工作正在进行中。

For the abutment with severe bone lost, pontic width reduction can significantly reduce the stress in PDL of it, and protect the health of remaining periodontium of abutment.

对于基牙牙槽骨高度降低的固定桥，桥体减径可以更加明显地降低基牙牙周膜应力，对桥基牙起到保护作用。
