一、前言建筑物地基除承受上部静荷载外,同时还常受到振动的影响,这时地基的容许承载力应如何确定,目前还未解决。设计人员常以为振动较小而不考虑其影响,从而造成了一些工程事故,因此这一问题亟待解决。国内外对振动条件下土的性能已有不少室内试验资料,但都不能直接用来确定地基承载力。我们曾先后在齐齐哈尔的两个工程中进行了大规模的长期振动荷载试验,由于对静荷载采用弹簧隔振,故可分别求得不同 I. INTRODUCTION In addition to bearing the upper static load, the foundation of a building is also often affected by vibration. At this time, the allowable bearing capacity of the foundation should be determined. It has not yet been resolved. Designers often think that the vibrations are small and do not consider the impact, which causes some engineering accidents. Therefore, this problem needs to be solved urgently. There have been many indoor test data on the performance of soils under vibration conditions at home and abroad, but they cannot be directly used to determine the bearing capacity of the foundation. We have conducted large-scale long-term vibration load tests in two projects in Qiqihar. Since the static load is spring-isolated, it can be obtained separately.
