摘要
本文以兰州市三座高层建筑为例,主要介绍卵石地基回弹、反力分布、箱形基础沉降观测、上部结构自振特性等问题的实测结果。并对实测结果进行了分析和探讨。同时还介绍了上部结构动力分析的成果。为深入研究卵石地基箱形基础及上部结构的工作机理提供了有价值的参考资料。
In this paper,three tall buildings'structures in Lanzhou are studied as examples far presenting the measured results of the resilience and the reaction distribution ofthe pebble subgrade.settlement observation of box foundation and the nalural vibrationproperties of the superstructure.The measured resultsare analyzed and studied. And theresults of dynamic analysis of superstructure are given.This Lest placides valuable reference data fo a more thorough study of the working mechanism of the pebble subgrade.boxfoundation and the superstructure.
