Stability Analysis of Horizontal Directional Drilling Borehole Wall in Pre-Reinforced Sandy Pebble Stratum
For the collapse of the sand and gravel stratum in the process of trenchless drilling hole , based on elasticity analysis with the elasticity theory of horizontal directional drilling hole wall, the stress states under different lateral pressure coefficients are analyzed after reinforcing the sand and gravel stratum which is prone to collapse. Meanwhile, the reinforcement requirements for maintaining the stability of the hole wall under different conditions are put forward. This study can supply the reference for the project of reinforcing the horizontal hole.
