摘要

了解土壤刚度的主要特征是岩土工程在过去30年中取得的主要成就之一。模量退化是目前研究的主要领域之一。了解非线性是基础设计中准确可靠地评估地面运动的必要条件。本文着眼于深地基沉降的评估问题，并描述了两种开发的方法，使设计人员能够考虑地基的非线性行为。第一种方法提供了通过全尺寸桩的反分析评估的现场刚度参数。第二个涉及从表征土壤刚度的退化曲线中推断土壤与基础相互作用的行为。

Pile-settlement evaluation using field stiffness non-linearity

Understanding the principal features of soil stiffness has been one of the major achievements of geotechnical engineering over the past 30 years. The study of modulus degradation is now one of the main research areas. Understanding non-linearity is essential in foundation design for accurate and reliable evaluation of ground movements. This paper looks at the problem of assessing of deep foundation settlements and describes two approaches developed to enable designers to take soil–foundation non-linear behaviour into account. The first provides in-field stiffness parameters evaluated by back-analysis of full-scale piles. The second involves deducting the behaviour of the soil interacting with a foundation from degradation curves characterising the soil stiffness.

期刊介绍： The objectives of the Association shall be the promotion of co-operation among geotechnical societies in SE Asia; and the assistance to member societies who have limited number of members. Now there is only one combined web titled: AGSSEA-SEAGS. SEAGS & AGSSEA encourage the submission of scholarly and practice-oriented articles to its journal. The journal is published quarterly. Both sponsors of the journal, the Southeast Asian Geotechnical Society and the Association of Geotechnical Societies in Southeast Asia, promote the ideals and goals of the International Society of Soil Mechanics and Geotechhnical Engineering in fostering communications, developing insights and enabling the advancement of the geotechnical engineering discipline.
