Abstract: With the rapid increase of pipeline laying projects across rivers, it is very necessary to scientifically analyze and evaluate the influence of horizontal directional drilling construction on safety of embankments in order to ensure the safety and stability of embankments when the horizontal directional drilling crosses the river.Based on the analysis of horizontal directional drilling constriction technology crossing embankment construction, a Bishop correction formula is proposed to analyze the disturbance degree of horizontal directional drilling construction process on embankment containning soft soil layer.We analyze the buried depth, diameter, earth-in angle, earth-out angle and embankment slope on stability of embankment in horizontal directional drilling crossing design.The results show that the first drilling construction has the greatest influence on the safety and stability of the backwater slope of the embankment, and it is suggested that the calculated value of safety factor of embankment during the construction period should not be less than 1.6;in the range of 12 times of pipe diameter, the buried depth of pipeline crossing has a great influence on the safety and stability of the embankment, however the influence could be neglected if exceeding the range.The influences of earth-in angle and earth-out angle are slight.
