芦山7.0级地震通讯系统震害调查分析

Seismic damage investigation and analysis of the communication system in Lushan M_s7. 0 earthquake

首先调查了芦山"4·20"地震后灾区内通讯系统的地震破坏情况,总结了通讯系统建筑物、基站、设备、光缆及信号发射塔的典型破坏特征,并对其破坏成因进行了分析。指出了影响通讯系统破坏的主要因素,最后结合调查数据和震害分析结果,对芦山地震中通讯系统的总体破坏情况进行了评述,为加深对通讯系统地震破坏特征的认识、掌握震害影响因素及实施震后恢复重建工作提供参考。

In this paper, the earthquake damage information of communication system in disaster area was investigated after the Lushan ＂4.20＂ earthquake. The main damage characteristics of each research object in the communication system were summarized based on the investigated data, and the causing reason for typical damage was discussed to find out the dominant factors that affect the damage level. At last a seismic damage commentary on communication system on Lushan ＂4.20＂ earthquake was presented based on the investigated data. The conclusion can be used to deeply understand the damage mechanism, grasp the influence factor for each damage characteristics and improve the rebuilding work of the communication system.
