Study on Mechanical Property and Displacement of Latticed Soil Nailing Support
Latticed soil nailing support is a new type of revetment structure,which combined lattice support and soil nailing.It effectively improves the global stability of the foundation pit.Currently,the theoretical research about this supporting method is still not consummate.In this paper,on the basis of soil mechanics and code,the stability of latticed soil nailing support are analyzed by the theory of the retaining wall,soil nail and the model of supporting piles.Then calculate the displacement in the limit state by elastic fulcrum method and the instantaneous displacement by layer-wise summation method.The total displacement can be calculated by the combination of the two displacements above,which is between 3.38mm and 15.43mm and close to the measured data.Simulate excavation and supporting process of the pit by finite difference method,analyze the mechanical property and displacement of latticed soil nailing support.Thus the theory of the calculation method to this supporting model is obtained,offering a reference for the similar projects.
