大官庄—双庄断裂对宿扬高速泗洪段地层分布的影响

The influence of Daguanzhuang-Shuangzhuang fault on stratigraphic distribution of Sihong segment of Suyang expressway

郯庐断裂带江苏段,总体走向为NNE,延伸长约170 km。对郯庐断裂带上大官庄—双庄断裂(F_2)进行研究,发现该断裂带断层在全新世早期有活动,宿州至扬州高速公路泗洪段场地受其影响,在里程K3+633.0~K6+822,工程地质勘察范围内地层分布变化巨大。

Jiangsu segment of Tanlu fault zone,whose overall trend is NNE,extends for about 170 kilometers. Research on the DaguanzhuangShuangzhuang fault（F2） on Tanlu fault zone,it finds that this fault zone was active in the early Holocene. The Sihong segment of Suzhou-Yangzhou expressway affected by the fault（F2）,the distribution of strata in the range of K3 ＋ 633. 0 ~ K6 ＋ 822 varies greatly within the scope of engineering geological survey.
