With China's rapid economic development, increasing high-rise buildings , as well as some multi-storey and underground garage to meet the requirements of use and civil defense , more and more based on using a box-shaped base . High-rise building box raft foundation technical specifications provided foundation coefficient compared with the actual use is also more convenient . However, the limitations of technical specifications , it is merely the foundation soil roughly divided into cohesive , soft soil and sand three categories, do not reflect the complexities of the foundation soil . Engineering and model test measured quantity is the norm there are a limited number of the root causes of this limitation . Later still need ongoing measurements and model tests , continue to accumulate information , and constantly enrich foundation coefficient table. For this specification focuses on the problems of land based on the sand box base substrate reaction model experiment , to further refine the specification of the foundation soil and reflects the regularity. First introduced the box-shaped test model based design and production . Determine the test model with the original structure similar ratio , model dimensions , reinforcement and other experimental parameters and produce the required test model . Secondly , a detailed account of the testing process to obtain experimental data . Again , the experimental data processing and analysis of results. Through the experimental data processing , sorting out land -based sand box aspect ratio on the basis of different substrate reaction force distribution curve , calculated reaction force coefficient basal plane , and the box-shaped base substrate reaction force distribution curve analysis, research box Foundation different aspect ratios , different box base plate thickness on the substrate reaction force impact . Finally, this paper describes the theoretical foundation and our current model substrate reaction coefficient method presented in this paper were used simultaneously sand land -based reaction force coefficient and the technical specifications given in the sand foundation coefficient calculation engineering examples , and comparative analysis . In its conclusions and recommendations are summarized in this experiment , obtained sand box foundation on land -based reaction force base Several important conclusions , and pointed out the lack of this experiment .
