Abstract
Since the mid1990s multistoried buildings highrise buildings and skyscrapers have been emerging due to the new round of greatscale development on the softsoil littoral Land subsidence in softsoil areas caused by engineering environmental effect especially by construction of highdense building groups attracts more and more attention The plot ratio may be one of the most important factors on engineeringinduced land subsidence Thus three geotechnical centrifugal model tests were conducted under three conditions of different plot ratios to study the ground settlement mechanism of highdense building groups in softsoil territory It is concluded that the subsidence superimposition effect is obvious in the central area of highdense building groups the settlement increases with the growth of plot ratio The urban planning department should take this subsidence situation into account when determining the construction plot ratio to utilize the earth more aptly and safelyThe work presented in this paper was supported by the research grant 4082178 from National Natural Science Foundation of China KwangHua Fund for College of Civil Engineering Tongji University and Shanghai Leading Academic Discipline Project Project number B308
