［摘要］四川長寧6.0級地震震區有6棟裝配式建筑，這些建筑距離震中約50km，所在區域設防地震烈度為7度（0.10g），鄰近的51YBT觀測臺站實測地震波峰值加速度為59cm/s2。經實地調查，這6棟裝配式建筑震后結構構件和連接部位未發現受損現象，主體結構完好，隔墻基本完好。其中項目一和項目二均采用了PC墻板，裝配率高。根據實測地震波計算分析結果，項目一在X向、Y向地震作用和項目二在Y向地震作用下的基底剪力超過了項目一和項目二在小震作用下基底剪力，項目一達到了抗規第1.0.1條“小震不壞”的設防目標；PC非承重墻板與主體結構連接方式對整體剛度有較大影響，建議在裝配式建筑設計中應考慮PC非承重墻板對整體剛度的影響，并加強PC非承重墻板與主體結構連接構造研究。

Abstract:There are 6 prefabricated buildings in the earthquake zone of Sichuan Changning M6.0 earthquake, which about 50km away from the epicenter. The earthquake intensity in the area is 7 degrees (0.10g). The peak acceleration of the seismic wave measured by the nearby 51YBT observation station is 59cm/s2. After on-site investigation, no damage was found to the structural components and connections of the 6 prefabricated buildings after the earthquake. The main structure is intact, and the partition walls are basically intact. Among them, Project 1 and project 2 both use PC wall panels, and the assembly rate is high. According to the calculation and analysis results of the measured seismic waves, the base shear of project 1 in this earthquake under the action of X-direction and Y-direction earthquakes and project 2 under the action of Y-direction earthquakes exceeded the base shear of project 1 and project 2 under the action of small earthquakes. The fortification goal of “small earthquakes not broken” in Article 1.0.1 of the anti-regulation has been reached for project 1. The connection method of PC non-load-bearing wall panels and the main structure has greater impact on the overall rigidity. It is recommended that the influence of PC non-load-bearing wall panels  on   the overall rigidity should be considered in the design of prefabricated buildings, and the research on the connection structure of  PC non-load-bearing wallboard and the main structure shoud be strengthened.
