Analysis on lateral bearing capacity of pile based on DMT

Based on dilatometer test result, the proportional coefficient of lateral resistance coefficient in pile's lateral soil, and the design value of single pile lateral bearing capacity is estimated. Then based on the result of pile lateral load test, the average value of horizontal critical load is worked out, and the proportional coefficient of of lateral resistance is figured out. Through the eontrast and analysis on the both of calculation results, their lateral bearing capacity are very close, but the proportional coefficient is different. It is deemed that it is not suitable to use the test pile's results in the calculation of project pile's lateral bearing capacity, it should be based on the actual condition, and eonsiders the efficiency of pile groups about the pile caps,piles and soil.
