| 摘要： | The overconsolidated crust of fine-grained sedimentary deposits may exert a significant influence on the performance of structures located in the near surface. The degree of influence depends on the thickness of the crust and its degree of development in comparison with the underlying deposit. The development of a crust is a result of the combined effect of chemical and physical processes acting in place. In this paper, the principal factors responsible for the development of surficial crusts and the resulting geotechnical characteristics of surficial clay crusts are described. Changes in intrinsic soil properties and the variable nature of surficial crusts produced are discussed. Examples from several sites are presented that illustrate the important consequences of crust development on the resulting geotechnical properties, and a description of the implications of the presence of a crust on design practice is given. |
