- Abstract:
- At 21:00 on May 21,2021,an MS6.4 earthquake occurred in Yangbi County,Dali Prefecture,Yunnan Province.A detailed survey was carried out right after the earthquake aiming at investigating the disaster of the communication system in the earthquake-stricken area.In this study,the general situation of the earthquake and the overall disaster situation of the communication system in the disaster area were firstly introduced.Then the characteristic damage phenomena of the base station controllers,base transceiver stations,communication tower and communication optical cable lines were reported in detail.Also,the emergency recovery of the communication system after the earthquake was introduced.Finally,some suggestions based on the disaster survey were provided to improve the aseismic performance of the communication system.These suggestions include:①Aseismic reinforcement should be carried out for the communication equipment without reliable installation; ②Aseismic design should be considered for the communication cable lines and the poles; ③Unified planning should be made for the construction of the communication cable lines and the electric wires in county areas; ④When the base transceiver stations are placed on the roof of the residential buildings,the carrying capacity of the roof panels should be carefully checked.⑤The damage of the nonstructural components should be paid attention to.
