摘要
文中依据孟加拉某电厂试桩工程基桩静载试验实测数据,采用中国、美国、印度关于桩基静载试验检测标准对其极限承载力分别进行判定并对比分析,结果表明按照美标Davidson准则确定的桩基竖向极限承载力值约为按照中国标准确定的极限承载力值的85%;按照印度标准确定的桩基竖向极限承载力值约为按照中国标准确定的极限承载力值的105%~110%;同等地质条件下基桩竖向极限承载力取值建议以不超过按照中国标准确定的极限承载力值为宜,以期达到安全、适用、经济的效果;按照美标与中标对单桩水平极限承载力的判定结果一致;按照印标判定的单桩水平承载力允许值约为按照中标判定的单桩水平承载力允许值的107%,建议同等地质条件下单桩水平极限承载力取值以不超过按照中标、美标确定的极限承载力为宜。
According to test piles measured data of vertical static load test of a certain power plant in Bangladesh,Chinese,American and Indian standards are adopted to respectively determine the ultimate bearing capacity of pile foundation with comparative analysis.The results of research show that the value of vertical ultimate bearing capacity of pile foundation determined according to Davidson’s standard is about 85%of that determined by Chinese standard;the value of vertical ultimate bearing capacity of pile foundation determined according to Indian standard is about 105%~110%of that determined by Chinese standard.It is recommended that the vertical ultimate bearing capacity value of pile foundation should not exceed the value determined by Chinese standard in similar geological conditions,so as to achieve safe,applicable and economic effects.The determination results of horizontal ultimate bearing capacity of a single pile are consistent with American and Chinese standards;the allowable value of horizontal bearing capacity of pile foundation determined according to Indian standard is about 107%of that determined by Chinese standard.It is recommended that the horizontal ultimate bearing capacity value of pile foundation should not exceed the value determined by American and Chinese standards in similar geological conditions.
