Remolded soils have a wide spectrum of liquid limits ranging from 25% to 412%. It is found that the remolded undrained strength is a function of water content and liquid limit. Furthermore, a simple index designated as normalized water content w * is introduced for normalizing remolded undrained strength for various soils. The normalized water content w * is the ratio of water content to liquid limit. The relationship between the remolded undrained strength and the normalized water content can be expressed by a simple equation. The new simple equation is not only valuable theoretically for helping in assessing the in situ mechanical behavior, but also useful to ocean engineering practice.展开更多

The undrained shear strength on the intrinsic strength line is different from the remolded undrained shear strength that is an important parameter for design and construction of land reclamation. The void index is used in this study for normalizing the remolded strength behavior of dredged deposits. A quantitative relationship between remolded undrained shear strength and void index is established based on extensive data of dredged deposits available from sources of literature. Furthermore, the normalized remolded undrained shear strength is compared with intrinsic strength line. The comparison result indicates that the ratio of undrained shear strength on the intrinsic strength line over remolded undrained shear strength increases with an increase in applied consolidated stress.展开更多

Burland introduced void index for normalizing the compression curves of various remolded and reconstituted clays to obtain the intrinsic compression line, which provides a reference framework to assess the in-situ compression behavior. However, it does not quantitatively account for the effects of initial water content on compressive behavior of remolded and reconstituted clays and the initial water contents of clays are not always limited to 1.0 - 1.5 times the liquid limits defined by Burland. A modification based on collected tests data was presented on the expressions of ?and ?defined by Burland. Extensive oedometer test data were also collected on various remolded and reconstituted soils with distinct liquid limits and initial water contents to verify the validity of modified expressions. A normalized compression line deduced by intrinsic compression line is proposed in the e-log p plot, which can be used to evaluate the effects of soil structure quantitatively on the intact compressive behavior for natural sedimentary clays.展开更多

Nonverbal communication (NVC) is an essential component of human verbal communication. Sometimes it is even more powerful and expressive than verbal interactions, for they can convey such subtle feelings and fine emotions that verbal entries feel impotent of. This paper intends to make a survey on the notion of nonverbal communication and further explore the function and the significance of body language on remolding teachers' behaviors in foreign language teaching.展开更多

As is shown by the logic of argumentation and the relational logic of process- oriented constructivism, the development of intemational norms may take another approach, one of origination, diffusion and remolding. Through dialogues on norms, discourse critique, self-remolding and other means, China has enriched the practice of remolding international human rights norms with a human rights theory centered on the right to survive and develop, thereby providing a new approach and new angle of vision that allows non-Western countries to break away from the monist approach of norm development.展开更多
