The stress changes induced by the construction of a system of embankments built over a soft clay deposit will be investigated using a special self-boring pressuremeter. The approach consists of combined experimental and analytical studies to evaluate the suitability of the self-boring pressuremeter and to study the effect of embankment construction on in-situ stress changes and anisotropy. The proposed program is feasible and should provide useful information for advancing the understanding of soft clay properties and improving pressuremeter test techniques. The PI has a solid background in the proposed research area. An award is recommended.

建造在软粘土沉积物上建造的路堤系统引起的压力变化将使用特殊的自钻式压力机进行研究。 该方法包括合并的实验和分析研究，以评估自钻孔式压力计的适用性，并研究路堤构造对原位应力变化和各向异性的影响。 所提出的程序是可行的，应该提供有用的信息，以促进对软粘土特性的理解并改善压力计测试技术。 PI在拟议的研究领域具有坚实的背景。 建议奖励。
