Short summary
The ground deformation of a typical reclamation area in Chongming East Shoal, Shanghai was monitored by the SBAS method. Moreover, corresponding the monitoring results to the soil properties with field investigation and laboratory tests. The soil properties including physical and chemical properties, compressibility, micropore distribution and microstructure characteristics, are studied, and then the monitoring results are reasonably interpreted, providing a reference for future construction.

Short summary
Channelized rock avalanches are a type of rock slope failures with massive flow-like movements of fragmented rock, which are potentially dangerous due to their strong mobility. This study built an empirical prediction model of travel distance using the Wenchuan earthquake dataset. The results suggest that the movement was dominated by the landslide volume, total relief and channel gradient. The model was tested by a separate dataset and proved to be useful in other regions as well.

Short summary
In Shanghai, China, land subsidence is distributed along the belt near a subway line. In order to figure out the mechanical response of the tunnel surroundings, the PFC2D software based on a discrete element method is introduced to simulate the section of the metro tunnel. The linear contact bond model was employed to reflect the characteristics of clay. The mechanical response law and subsidence mechanism were investigated.
