Yuan X., Li J., Dai Y., Rui K., 2018, The Influence of Ground Settlement Caused by Shield Construction Under Different Geological Conditions, Chemical Engineering Transactions, 66, 475-480.
The Longjiang Railway Station to Yunnan Road Station of Nanjing metro line four crosses three different geomorphic units.The Peck formula is fitted to the measured data of the effective monitoring points during the construction of the shield. By analyzing the typical curve, the shape characteristics of the settlement on different geomorphic units are obtained. Statistically analyzed the large number of width coefficient of settlement and its control parameters by fitting. Obtain the empirical value of the width parameters of the settlement under each geomorphic units. And predict the impact range of the settlement under different geomorphic units. The average width settlement value of the Yangtze River floodplain is 12M and the K value is 0.381.The average width settlement value of the ancient Qinhuai River is 11.3M and the K value is 0.313.The average width settlement value of the first grade terrace of the Yangtze River is 9.96M and the K value is 0.303.
