| 摘 要： | 根据张家界陈家溪石拱桥的现状及其检测报告，该石拱桥拱圈开裂、桥台向后滑移严重，存在危险性，由于该桥是进入市区的交通要道，需借助软件ANSYS模拟计算，对该桥进行维修与加固。加固方法主要采用基地压浆、化学灌浆法修补裂缝、增设拱圈等，为今后石拱桥加固施工提供工程借鉴。

| Abstract: | According to present situation and detection report of Chenjiaxi rock-arched bridge of Zhangjiajie, it is so dangerous to the bridge that the arch ring has cracked, and the bridge abutment backward slipped serious. Besides, the bridge is vital communication lines to city. By means of ANSYS software＇s simulation calculation, it is necessary to maintain and strengthen for that bridge. The main strengthening measure are as follows, base grouting, chemical grouting method repairing crack, adding arch ring and so on. This strengthening construction technology also provides certain basis for new rock-arched bridge strengthening. |
