Abstract

Abstract

By analyzing elastic-plastic state of horizontal soft soils hole wall,the stress state of the horizontal soft soils hole wall und er the earth pressure and the lama pressure are both analyzed,and the conception of the best lama pressure is pointed out.This study can supply the reference in practice of horizontal directional drilling.
- horizontal directional drilling（HDD）,
- stabilization,
- lama pressure,
- plastically deforming area,
- the best lama pressure
