ABSTRACT: Based on two sets of model tests, ground reaction pressure of L-shaped high-rise building with large-area thick raft foundation is studied. The results show that the effective load area on the raft is larger than the actual upper load area under the interaction of super-structure. The effective area includes the triangle area due to the combined action of two wings of L-shaped Tall buildings. The weak raft foundation area of L-shaped Tall buildings locates at one annex outside of the triangle area with combined action. From the test data, the contact pressure center of raft foundation under main structure of the L-shaped building locates at the corner of the area, the contact pressure under main structure distributed uniformly. Moreover, the combined analysis method based on principle of superposition is available to calculate the contact pressure of large thick raft foundation of high-rise buildings.

RÉSUMÉ: fondations sous la structure de LARGE-AREA THICK RAFT dans le bâtiment L-SHAPED TALL. Selon les études, avec zone triangulaire en fonctions combinées, aux limites des deux ailes du bâtiment L-SHAPED TALL, constitue la essais, pour les fondations du bâtiment principal de L-SHAPED TALL, son centre de la pression de contact est situé près du coin de sa structure L, et elles contact que ressentent les fondations.
