单桩承载力地理信息系统应用研究

Study on Application of Geographical Information System of Bearing Capacity of Single Piles

在对广东省肇庆市971根试桩的静载试验资料统计分析的基础上,建立了单桩承载力地理信息系统和单桩承载力数据库,并且利用该系统对971根试桩静载试验资料进行详细分析,在此基础上提出了肇庆市计算嵌岩桩的单桩极限承载力时,极限侧阻力、端阻力标准值的建议值。

The paper analyses the static load test data of 971 test piles in Zhaoqing. The geographical Information System of bearing capacity of single piles and the database of bearing capacity of single pile are set up for this foundation. According to the result of static load test data of these 971 piles, the paper gives the suggestive values to calculate the ultimate carrying capacity of rock-socketed piles, such as the characteristic values of the side friction of soil along the pile shaft and the end bearing.
