| 4. | After that , we went to a local " taoism " temple , the main arch way entrance actually forms a " tao " chinese character
之后参观了当地的道观，入口的拱门具有中国传统"道"家风格。 |
| 5. | For the damage of the main arch - ring elements , this paper uses the relative change of first order strain mode before and after the damage
对于拱肋的损伤，本文采用拱肋单元在结构损伤前后一阶应变模态的相对改变量来实现。 |
| 6. | Utilizing adjustable brace and dismantling of bowel support in batches , the stress of support and main arch circle is more reasonable in the process of system transformation
利用碗扣式支架的可调托撑，采用多点分批卸落，使支架和主拱圈在体系转换过程中受力更加合理。 |
| 7. | The effect of pouring arch circle to support ' s deformation is studied . the pour sequence of main arch circle is laid down by the principle that support ' s deformation is minimal in the process of pouring concrete
研究了拱圈浇注对支架变形的影响关系，遵循分段灌注顺序应使支架在混凝土灌注过程中变形幅度最小的原则，制定了主拱圈灌注顺序。 |

| 9. | Timely monitor of their stress in each working conditions can ensure the safe of support and main arch circle with full - automatic data acquisition system . the results of dynamic - load and dead - load test of the bridge indicate that the main arch has enough strength and rigidity and reachs design requirements
使用全自动数据采集设备和处理系统，对每一工况下的支架、拱圈应力进行适时监控，确保了施工过程中支架和主拱圈的安全。成桥静动载试验表明许沟大桥主拱结构具有足够的强度和刚度，达到了设计要求。 |
| 10. | The paper build a plane model of the whole bridge based on the fem , and analyze the internal force and structural displacement changes in every damage circumstance . the data reflect that the damages in arch rib in the tip will make internal force of some sections increased , accordingly the stability and the durability of the structure reduce ; the damages in the arch foot will change the structure system ; and the displacements of abutments will develop great accessional internal force , and deform the main arch and even crack , accordingly change the system of the structure
论文建立了全桥的平面有限元模型，分析了在各种病害情况下全桥的内力及结构位移的变化，计算数据反映了，拱顶拱肋损伤会造成某些截面的内力增大，结构的稳定性和耐久性降低；拱脚损伤可能引起结构体系改变；墩台位移会使上部结构产生较大的附加内力，使拱圈变形甚至于开裂，从而导致结构的受力体系发生改变等。 |
