Effect Study of Expansive Soil Slope Reinforced with Geogrid
Large scale pull-out tests are adopted first to study the frictional charateristics of geogrid and expansive soil, and a simplified interface model of geogrid and compacted expansive soil is suggested and the related parameters are given. Based on the tri-axial test results, FLAC3D is applied to numerically analysize stress and deformation of the expansive soil [...]
Study on the Deformation and Strength Behavior of Coarse Grained Soil Reinforced with Geogrid
The pervious reseach indicated that upper part was failed firstly when earth-rockfill dam was damaged under strong earhtquake loading.It is necessary to use earthquake-resistant measures to high earth-rockfill dam in earthquake region.Some design plans of earth-rockfill dam in strong earthquake area(lianghekou,shuangjiangkou,ect.) has started to use the geogrid as a measure of slope reinforcement,in recent years.However,this [...]
Experimental and Numerical Simulation Study on Pullout Behavior of Geogrid under Clay
It is known that soil is good at compression resistance but bad at shear resistant.These characteristics make a huge limitation of soil’s engineering applications.Therefore,laying geogrid in slopes and retaining walls is a new technology in geotechnical engineering recently which is developed quickly,now the design method of reinforced soil structure is also built on the theory [...]

Experimental Study and Design Method Research on Geogrid Reinforced Embankment
Natural soil, as a type of geological material, has very low tensile strength. However, in some actual projects it is possible for soil to resist against potential lateral load, such as retaining wall structures. In order to improve soil’s tensile strength, some material, for example, steel bars and geosynthetics, are often put into the soil, [...]
Research on the Geogrid Solving Bumping at Bridgehead in Liuqian Highway
In the Advanced Highway disease in Bumping at bridgehead is a common problem. Paper first Bumping at bridgehead phenomena and the causes of uneven settlement of the bridgehead and hazard were also discussed, proposed several methods to solve differential settlement, focused on analysis of project characteristics and geogrid reinforcement mechanisms. Experimental control through indoor grille [...]
Seismic Performance of Geogrid Embankment
The embankment stability is brought out because of many mountains and frequent earthquakes in our country and the seismic stability of the embankment engineering is looming larger with the embankment being built in highly seismic regions when the strategy of developing the West is implemented. The seismic hazard investigation of Wenchuan earthquake shows that none [...]
