Keywords: monolayer cable net; suspended chain line; algorithm; pre-tension; replacement beam.
To solve this problem, generally the structure engineers iteratively computes by using finite element software to identify the diameter and pre-tension of the tension cable based on the deflection limit and related engineering experiences.
Considering experience difference of engineers and computing cost, frequently a bigger tension cable is selected, so it leads to waste.
The deflection is smaller than the deflection control for 3 equal parts and the results meet the engineering design requirement

Keywords: siol nailing overloading numerical analysis FLAC-3D
Abstract.
Based on an engineering example,the FLAC-3D was applied to set up numerical analysis,analyzing the influence of the overloading acting position and the magnitude on the horizontal and vertical displacement of the foundation pit.Some useful conclusion was obtained,which will offer reference to the design and construction of the soil nailing.
General engineering The project of soil nailing was a full-scale in-situ test done by C.K.Shen[3].There is sandy silt and silty clay in the site,in which the water table is located 18.3m below the ground.
Figure 7 Shear strain rate of pit Figure 8 Shear strain rate of pit(q=19kPa) Summary 1) it is feasible to analyze the engineering with FLAC-3D; 2) the horizontal and vertical displacement of the foundation pit is small when the position of the overloading get far away from the edge of excavation pit, the overloading of pit deformation can be ignored when the position far away from a certain distance; 3) when overloading is small, its effect on the deformation of pit can be ignored , but when the overloading is large enough,adverse effects must be considered.
