Outfield tests on bearing capacity of general homogeneous soil ground.

In order to judge, the bearing safety of homogeneous ground that the heavy forcing plates acted on, static and dynamic outfield tests were carried out. According the static plate loading method, the outfield test that bearing plates simulating the static procedure of heavy forcing plates was performed. By the similarity criterion Π theorem, the pneumatic impact test of reduced proportional plate simulating the dynamic procedure of forcing plate was completed. Based on the outfield tests, the paper studied the S - t curves that express the variety of settlement with time, the P - S/D curves that express the soil settlement correlative relation among bearing plates with different sizes under the corresponding load, the P - S curves under static and dynamic loads as well as the contrast between them. To the homogeneous soil ground in outfield tests, S - t curves indicate that the static load method is reasonable, and P - S/D curves appear a linear proportional relation in the limit load range. The settlement under dynamic load is much less than that under static load. The deformation stiffness under dynamic load is higher than that under static load. The settlement caused by instant dynamic impact can be ignored. [ABSTRACT FROM AUTHOR]
