On March 10th,2011,a Ms 5.8 earthquake struck Yingjiang County,Yunnan Province.The seismic intensity of Yingjiang Embankment Project near Yingjiang County is 8 degrees.About 38.4 kilometers of embankment was damaged during the earthquake.Based on the comprehensive analysis of regional seismic,geological conditions and seismic damage characteristics,a conclusion is drawn that the Yingjiang Embankment Project is located at the intersection between north-south and north-east fault zones,seismic tremor is the external cause,and fine sand foundation is the internal cause.To guarantee the safety of life and property and to facilitate the construction,some measures are applied.The cracks of the embankment can be processed by the conventional replacement and rolling compaction,while the piping leakage of the embankment can be processed by covering gravelly soil outside the embankment and revetting with rubble inside the embankment.The measures accumulate experience for emergency disposal of embankment project in the Nation.
