In order to resolve the problems of drawing borehole histogram at present��a new method is pro- posed by using the elasticity- nonlinear programming theory to adjust the text location of borehole histogram�� The ini- tial borehole histogram was visualized by properly allocating the blank cells of soil descriptions�� The x i coordinates of engineering geological descriptions in the histogram are optimized and calculated�� Based on the x i results��Auto- CAD is used for re- developing the borehole histogram automatically�� This new borehole histogram drawing method is professional and efficient��which can produce standard drawings��reasonably distributed descriptions and fine for- mat without subsequent processing��so lots of labor cost can be saved��
