Research On Mechanical Properties And Ecological Functions Of Spray Seeding Basis Material

With the rapid development of highway, environmental issues become a topic ofconcern increasingly. While highway modernizes process at the same time，cutting itsexcavation and masonrying embankment will cause some negative impact tohydrogeology, native flora and fauna habitat along. How to restore the ecologicalenvironment along quickly and effectively becomes a conundrumthe to theconstruction of highways, spray seeding basis material cames into being in thisbackground. Good spray seeding basis material can effectively improve the barerocky slopes, soil erosion and plant community along, to minimize the adverse impacton along as the construction of high4ways. However, the spray seeding basismaterial just has more than ecological functions, it should have some resistance toerosion,so this article does the following works:(1)Using the orthogonal principle to direct shear spray seeding basis undernatural state and saturation, analysis spray seeding basis material’s cement content (0,3%,6%,9%and12%), cement age (1day,7days,14days,21days and28days) andfiber content (0,1%3%,5%and7%) of the weight, geting the optimal ratio undernatural and saturated state of two optimal proportion is12%cement content,3%fibercontent and9%cement content,0fiber content.Measuring the pH of the sprayseeding basis material under natural state.(2)Using the orthogonal principle to discuss the relationship between the materialof cement content(0,3%,6%,9%and12%), cement age(1day,7day,14day,21dayand28day) and fiber content(0,1%,3%,5%and7%) with the spray seeding materal’sunconfined compressive strength under natural and saturation, getting the optimalratio of the unconfined compressive strength is12%cement content,3%fiber contentand12%cement content,7%fiber content.(3)Using the orthogonal principle to planting bermudagrass in spray seedingbasis material, analysis spray seeding basis material’s cement content (0,3%,6%,9%and12%), cement age (1day,7days,14days,21days and28days) and fiber content(0,1%3%,5%and7%) of the weight about the growth of bermudagrass, geting theoptimal ratio is3%cement content,1%fiber content.(4)Comprehensive analysis of the spray seeding basis material’s cohesion,unconfined compressive strength and bermudagrass growth composite indicatorshows that spray seeding basis material’s ratio greater impact on its consolidatedevaluation value.11#,19#,21#and22#spray seeding basis material have greater scoreunder natural state.11#,21#and22#spray seeding basis material have greater scoreunder saturation.11#,21#and22#spray seeding basis material’s ratio should be usedinto actual project.
