在竖向荷载作用下,基于单桩沉降简化计算方法的基础上,将群桩沉降量看成由桩身压缩量与桩端土层压缩量组成,而桩端土层压缩量考虑桩与桩之间的相互作用,给出了基于相互作用系数的群桩沉降计算式,可以反映距径比、长径比,桩数和桩周土层等特性。通过实例计算表明该计算方法具有足够的精度。 Under the vertical load, based on the simplified calculation method for single pile settlement, the pile group settlement amount is regarded as being composed of the pile compression amount and the soil compression at the pile end, and the pile end soil compression amount considers the pile and pile. Based on the interactions, the calculation formula for settlement of group piles based on the interaction coefficient is given, which can reflect the characteristics of distance ratio, length-diameter ratio, number of piles and soil layer around the pile. The example calculation shows that the calculation method has sufficient accuracy.
