Abstract Soil bioengineering technique (Brush layering) that uses vegetation as structural element achieved reputation in the modern world due to their ability to combine safety and environmental conservation elements. In order to figure out the consequences of plant roots on land sliding it is vital to understand the mechanism of root anchorage in soil slope. Moreover this research portrays a list of pull out tests to determine the plant root-soil mechanical interactions. The artificial root models were developed based on simple roots pattern. In this test the response of root branching patterns towards pull out test while subjected to lateral force using artificial root models were observed. The research exposed the influences of number and angle of lateral roots in a root system on the ability of the plant to resist the force. In addition to that when the moisture content was raised, it was noticed that the pull out resistance force decreased. Having said that this research focused on the effects of brush layering and its displacement on different loading condition.
