The disaster area of the Pishan M_S6.5 earthquake in 2015 is located in the southern margin of the Tarim Basin,where the natural condition are harsh,and the economy is extremely backward.Moreover,because of a large number of residential housing with poor seismic performance in the disaster area,the damage and economic losses are serious.Since the most disaster area is located in the piedmont overflow,with poor site conditions such as shallow groundwater level and soil foundation,the magnifying effect of ground motion has a significant impact on the damage.In conclusion,we believe that investment in antiearthquake housing projects should be increased in post disaster reconstruction.Furthermore,for the north of the disaster area,with the dense population,poor conditions like soft soil foundation and poor engineering geological conditions,we recommend that in the future construction of anti-earthquake housing projects,more attention should be paid to strengthen the foundation treatment and precaution measures.
