摘要
通过对建筑物施工过程中基础下碎石桩加固地基的应力和孔隙水压力的原位观测,获得了非常有益的数据。试验表明:建筑物基础下观测到的应力和桩土应力比变化规律与静载荷试验中载荷板下观测到的结果基本一致,施工期地基土中孔隙水压力不但增长幅度不大,而且消散很快。
Valuable data were obtained from field observations on back-pressures and pore water pressures in composite foundation with stone columns during construction of a building. The measured back-pressures under the foundation and their stress concentration factors were in good agreement with those from the loading tests. It is shown that the monitored excess pore water pressures during construction do not increase greatly but dissipate quickly.
