The Yangtze River Delta

The Su-Xi-Chang area is located in the Yangtze River Delta in southeastern Jiangsu Province, China. More than 2 m cumulative land subsidence has occurred since 1980s. A range of monitoring programs, geological investigations, and numerical modeling has been implemented in order to establish a regional rehabilitation plan. In this paper, the column element settlement model (CESM) has been established to investigate the coupling effect of soil self-weight, upper loads, and groundwater withdrawal on land subsidence. The model has been verified by comparing with the land subsidence records in Changzhou and further applied to the investigation area. The results show that extensive groundwater withdrawal is the main cause of the land subsidence. Settlement caused by soil self-weight increases with the depth and decreases with upper loads, while settlement caused by upper loads increases with the intensity of upper loads and decreases with depth. The proportion of ground settlement caused by soil self-weight, upper loads, and groundwater withdrawal is also investigated.

Column Element

Owing to strong nonlinearity of shotcrete and difficulty of determining the equivalent material properties of steel-shotcrete composites for numerical analysis, methods are required to estimate nonlinear behavior of steel-shotcrete composite in the computational aspect efficiently. In this study, the behavior of steel-shotcrete composites, main primary supports in the NATM tunnel, are estimated by finite element method using the fiber beam-column element. The numerical results are compared with results of uniaxial and flexural test. Results of comparison show that finite element analysis of using fiber beam-column element can be an efficient tool of estimating the steel-shotcrete composite as the primary support in the NATM tunnel.
