英文摘要	The extended geometric shape of soil crack is an important factor in the strengthening design of split grouting, but the occurrence and development of soil split grouting is difficult to be visualized. This paper studies the cracks form of splitting grouting, establishment of the failure criterion and determination method of crack from the point of fracture mechanics. In order to establish the finite element model of crack extension we employed ABAQUS software together with engineering parameters of soil reinforcement from Lanzhou New Area fast road project K1 + 662.053. We also analyzed the crack length and effect of split grouting pressure and the impact of soil physical and mechanical properties. This research report demonstrates that when calculating split grouting pressure we should take the impact of crack extension length and soil strength parameters into major consideration. Crack length is affected dramatically by grouting pressure in which it shrinks non-linearly as the crack length increases. © 2017 Institute of Thermomechanics CAS, v.v.i.
