Vacuum-Heaped Load Combining Precompression Study In Consolidation & Seepage

This dissertation introduces the necessity, mechanism and developing of the vacuum-heaped load combining precompression in the Consolidation of the Soft Highway foundation . Based on the Terszige and Biot theory , initially analyze the economical of this experiment , directly save investment 22% after compute . After that , computing the settlement of highway foundation , comparing the computing and survey value , the predict formula of vacuum-heaped load combining precompression for designing ,this formula show that the distortion law of consolidation progress . At the same time , based on the position and room experiment, analyzes the intension transformation in soft soil and criteria of stabilization control . This paper emphasize study the seepage of vacuum-heaped load combining precompression., deduce the drainage quantity computation formula for stage loading in soft soil. An example show that the results of calculation are in good agreement with the measured value , this explain that the formula is rational.
