LTD, China The buildings of the Confucius Institute and the Institute of Media and Art in Mozambique adopt a frame structure. Due to the building function and the architect's personalized modeling requirements, the project has a large planar opening area and a large span structure. We have completed the engineering structural design of the jump column and the foundation design of the geological conditions under which the self-weight collapsible soil. In addition, we also compared and analyzed the reinforcement of the calculation column of the "model column" method and the modified expansion coefficient method, checked the failure strength and stable ultimate bearing capacity, and also concluded and summarized the results for the design of foreign aid projects. Midas GTS software was used for foundation settlement analysis of self - weight collapsible sand. http://pubs.sciepub.com/ajcea/6/5/7/ajcea-6-5-7.pdf slender column instability failure model column method modified expansion coefficient method self-weight collapsible sand
