Abstract: The geomorphology of Shanghai rolling hills is complex, which is divided into high hills and low hills, due to the erosion and the deposition processes by rivers, ocean, lakes and marshes. Then, how to control the differential settlement of soils in the rolling hill terrain? This paper studies the safety and technique aspects of the landscaping, which is constrained by the subsurface conditions as well as unknown hazards. This paper presents a landscaping technique for a villa project in the western suburbs of Shanghai. Through summarizing the research background of the project, the problems of landscaping hills are evaluated. On the basis of briefly describing the construction sequence of the project, the design process is demonstrated in detail. Among them, the entire process of the landscaping construction also includes the comparison and selection of analytical methods, proof load test to failure, potential hazards evaluation, the piled foundation design to minimize the potential risks as well as the post construction differential settlement evaluation. These results have an important reference value for the construction projects in soft soils.
