【Abstract】 In this paper,the hazardous geological factors in Xuzhou city,such as surface and underground karst landscape, groundwater funnel, mobile fault, soft foundation, Huanghe flood sediments and steep slope are analyzed. These factors can be divided into three kinds: obvious,obstructive and potential. Depending on engineering geological method and scientific plan,we can decrease the risk of these hazardous factors.更多还原
