摘要
针对《建筑桩基技术规范》推荐的m法,通过上海地区大量单桩水平试桩资料验证了m法在上海软土地区的适用性,通过试验资料对m值进行了反算,并与上海《地基基础设计规范》以及《港口工程桩基规范》推荐的m值进行比较;分别选择灌注桩和PHC管桩不同桩型的试桩资料,通过m法与实测弯矩以及其他计算方法比较,结果表明采用m法计算确定单桩水平承载力对上海软土地区建筑桩基是适用的,计算桩身弯矩曲线与实测曲线比较吻合,m值建议可按上海《地基基础设计规范》中规定范围的上限取用。
As for the m-method recommended by China's technical code for building pile foundation, the applicability of the method in Shanghai soft soil area is validated by means of test data of single pile. The m value is back-calculated based on the test data, and it is compared with that suggested by Shanghai's foundation design code and China's code for port foundation of harbour engineering. The data of cast-in-place piles and PHC piles are selected to compare the values by m-method with the measured bending moments as well as the results of other methods. The results show that the m-method is applicable to determine the horizontal bearing capacity of single pile in Shanghai soft soil area. The curve of the calculated bending moment aggress with the measured one. The m-value is recommended according to upper limit stipulated by the Shanghai's foundation design code.
