motivation letter 1 Dear professor, My name is Heibin Cheng, a third-year graduate student majoring in Geological Engineering at Guizhou University. During my undergraduate education, I mainly studied Civil Engineering in Wuyi University. I plan to further study the PhD program of Geotechnical Engineering of your esteemed Technical University of Catalonia. During previous three years’ study, I was diligent and conscientious at my courses and I developed my own way of learning. Apart from studying major courses, I had take part in the research of laboratory physical model of rockfall runout distance and my dissertation topic is The Influence of Fine Grain Content on Gravel Soil Shear Strength in GuiZhou Karst Area. To Conduct research, I have done some rock and soil tests which needs a lot of manpower, material and financial resources, especially, the big-scale shear test. Although the progress of test is full of hardships, I do enjoy its difficulties. In my opinion, although those research areas I focus on are basic research, it are no doubt that they play an instructive role in Geotechnical Engineering, including the stability of rock masses and soil, the slope treatment, the tunnel stability, highway engineering and so forth. From these research experiences, I clearly understand that my research interest lies in Geotechnical Engineering and I have decided to further study these related areas. Geotechnical Engineering in UPC based on a set of prominent and well balanced lectures that not only promote individual professional skills and cultivate their ability but also their creativity, management level and shape attitude. I think I can get more professional knowledge than I can get inland and extend my knowledge fields to enhance my competitive strength.
