摘要
通过专门的试验设备对某工程大直径灌注桩进行了现场试验,分析了其承载特性。根据试验得到的一些不充分的数据,利用灰色系统理论确定试桩沉降的数学模型——GM(1,1)模型,对实际工程进行了预测,结果证明本模型与实测结论吻合良好,预测精度符合要求。
Some on-site tests have been done on a large-diameter cast-in-situ pile with special equipment, with bearing characteristics analyzed. Based on the insufficient data obtained from tests, a mathematical model of the test pile＇s settlement--GM （ 1, 1 ） model was established with gray system theory. The test pile＇s settlement was predicted with the model, it was found that result obtained with model is in accordance with that from the actual measurement.
