The Effect Of Dense Layer Bolt To Rupture Surface In Soil Slope

Bolt retaining wall is used to maintain slope stability measures. The main load of earth pressure as slope retaining structures to withstand. It had become a key factor that determine the anchor rod and retaining wall stability. It has been attracting the attention of a large number of scholars in the country and abroad. The general condition, people used coulomb theory to calculate the retaining wall’s fracture surface. Engineering practice prove that in the case of dense layer of soil slope anchor, the retaining wall’s rupture surface is not match coulomb theory. So in the case of dense layer of soil slope anchor, classic earth pressure to rupture surface was optimized for future applications in engineering is very necessary and meaningful. The main analyzes as follows:①According to the limit equilibrium theory, to make depth analysis and research in the dense layer of soil slope retaining wall. Calculate the actual results of the coulomb earth pressure theory and distribution of soil pressure, and stress the need for soil amendment.②Based on static balance method or the equivalent beam method, used these two theory to calculate the internal forces rib pillar and anchor of the internal forces. In order to carry out the rib pillars and retaining plate and bolt design, as to obtained in the case of soil slope retaining bolt overall design.③Briefly describes the basic principles of the reinforces soil retaining walls and the anchoring mechanism dense layer of soil slope retaining wall. Analyzed the stress mechanism reinforced soil retaining walls and dense layer of soil slope retaining wall anchor. Combine the engineering practice in dense layer of soil slope retaining wall’s anchor bolt pullout force at all levels. Get the each measuring point reinforced stress test results for data analysis. Concluded that: under the same external conditions, the rupture surface of anchor rod retaining wall is similar with reinforced earth retaining wall.④Used The Plaxis software to contribute the model about retaining wall theory and potential failure surface, and calculated mesh deformation diagram of the fracture surface, and the potential failure surface under the retaining wall of the total displacement maps. Through comparative analysis of specific parameter values under two fracture surface. We can concluded that in the case of potential failure surface laid anchor, retaining wall displacement is very small, the soil does not damage, so it is safe.⑤We used the Phi-c reduction calculation to calculate the fracture surface. Get the shear strain diagram reduction operations, through shear strain diagram. We can know that dense layer of soil slope failure surface is no longer anchored retaining Coulomb theory of rupture surface, but with reinforced soil retaining wall mansard fracture surface is very similar.⑥Describe the construction of the basic processes of soil slop retaining wall. Detailed analysis of the project Bolt common diseases, and propose appropriate measures to deal with bolt diseases. Introduction existing traditional construction techniques about mortar anchor, and introduced the hollow grouting anchor since construction, the construction process will work in two soil characteristics were compared. At last, pointed self-advanced technology of hollow bolt grouting advantages for the future anchor construction for reference.
