摘要
水泥土的无侧限长期抗压强度是水泥土搅拌桩复合地基设计的重要参数。搅拌桩水泥土的无侧限长期抗压强度与许多因素有关,而这些因素又是不能确定的,因此可以将它作为一个灰色系统来研究。该文建立了水泥土长期抗压强度GM(1,1)灰色预测模型,并进行了精度评价,实践证明,灰色理论能够对水泥土长期抗压强度进行预测,且具有可靠的精度。
The long-term unconfined compression strength of cemented soil is the important design parameter of cemented soil mixed pile composite foundation. It is related to many factors, and these factors couldn＇t be determined, so the long-term unconfined compression strength of cemented soil may be studied as a grey system. A GM（ 1,1 ） model to predict the long-term compression strength of cemented soil is established in the paper. The practical examples show that grey system theory can predict the long-term compression strength of cemented soil with high precision.
