Introduction Geotechnical model test plays an important role in the study of soil mechanics, it's not only, provides an effective way to verify and improve soil deformation and strength theory, but also for geotechnical engineering design.
Physical model is the real physical entities, at the condition of meeting the basically similar condition, the geological structure and engineering structure of the spatial relations will be more accurately reflected by physical model, and more intuitive test results[3], Based on the similitude theory, this paper makes an in-depth research on the process of formation and development of the mechanical behavior which are the process of strip foundation failure.

Experimental Research of PCMs - TH29 Using on Building Energy Storage Lin QIU 1, a, Runping Niu1, b, Zhi Tan 1,c 1 Beijing university of civil engineering and architecture, Beijing, China aqiulin@bucea.edu.cn, b niurunping@bucea.edu.cn, c tanzhi552@sohu.com Keywords: Phase change materials , hydrated salt , TH29, building energy storage, thermal characteristics.
It shows that TH29 on the thermal characteristics of melting and solidification of the experimental conditions is stable, this stability of TH29 Is better for the practical engineering applications, the long-run can still meet the indoor temperature design requirements. 4.Delayed effects Temperature curve of phase change materials center position and edge position shown as Fig.6, It can clearly see temperature hysterics from the center to the edge in the process of phase change; The beginning of phase change gradually lag from the D point to the A point; isothermal phase change solidification process duration gradually extended.
That is the PCM TH29 can maintain a stable thermal characteristics for the practical engineering applications.
