Geocell protective slope is a kind of important ecological protection form, which is widely used in the geotechnical engineering field. Based on the finite element software ABAQUS, and combining with protective slope body’s mechanics performance in shallow soil, the finite element model of geocell slope protection is established under the conditions of rainfall seepage, and then we simulate the...
With the standard of living in China is improved constantly, construction expressway northeast Chongqing has also witnessed a rapid growth. The process mountain road, cuttings and embarkment road would definitely cause distortion movement high slope create large amount lose sand, which seriously threat safety slopes. Meanwhile, engineering causes destruction original vegetation, hard to restore...
چکیده مطالعه ویژگی های مورفولوژیکی ، میکرومورفولوژی، فیزیکوشیمیایی و کانی شناسی خاک ها در یک ردیف پستی و بلندی در منطقه کوهین قزوین پریسا حسینی برای حفظ اراضی و افزایش امکان بهره برداری از خاک، آگاهی از ویژگیهای مختلف خاک ها ضروری است. در این تحقیق ویژگی های مورفولوژیکی ، میکرومورفولوژی، فیزیکوشیمیایی و کانی شناسی خاک ها در یک ردیف پستی و بلندی در منطقه کوهین قزوین در شهرستان قزوین مطالعه و ...
Taking the slope of Suiyu Railway to study, the research separately studied soil resistivity, soil electrochemistry (corrosion potential, oxidization reduction potential, electric potential gradient and pH), soil anions (total soluble salt, Cl(-), SO4(2-) and ), and soil nutrition (moisture content, organic matter, total nitrogen, alkali-hydrolysable nitrogen, available phosphorus, and availabl...
Protection of slope and embankment from erosion has become an important issue in Bangladesh. The constructions of strong structures require large capital, integrated designing, high maintenance cost. Strong structure methods have negative impact on the environment and sometimes not function for the design period. Plantation of vetiver system along the slopes is an alternative solution. Vetiver ...
