Abstract
To address the uncertainty in bearing capacity of cast-in-place piles under complex foundation conditions,this study conducted field static load tests based on actual engineering scenarios.Results demonstrate that increasing pile length significantly enhances bearing capacity,with end resistance contributing 32%～35%and unit end resistance increasing by 44.3%.Lateral resistance exhibited full functionality in hard soil layers.Measured values exceeded code requirements by 17%～24%.It is recommended that in similar complex foundations,the characteristic value of end resistance for strongly weathered rock should be set at 1.1～1.2 times the code value,while lateral resistance for hard plastic clay should be set at 1.1～1.15 times.Particular attention should be paid to the adverse effects of weak interlayers on horizontal bearing capacity.关键词
