摘要
工程经验表明,在砂性土地质条件下,采用静压法进行预制桩施工时,由于沉桩阻力过大,时常出现沉桩困难等问题。因此,在施工过程中,对静压施工沉桩阻力的计算十分关键。对6根桩在不同入土深度时的压桩力进行分析,确定了砂性土条件下静压沉桩阻力估算深度修正系数计算公式。结果表明,公式计算结果与试桩试验结果更吻合。
The engineering experience shows that when the static pressure method is used for precast pile construction under the condition of sandy soil,it is often difficult to drive the pile due to the excessive pile driving resistance.Therefore,the calculation of pile driving resistance in static pressure construction is very key.In this paper,the pile pressing force of 6 piles at different soil depths is analyzed,and the calculation formula of depth correction coefficient for estimating static pressure pile sinking resistance in sandy soil is determined.The calculation results of the formula are more consistent with the test results of test piles.
