B. montmorillonite C. Yi Li Shi D.. 5. the soil permeability coefficient, K value is the smallest (D) A. sand B. silt C. silty clay D. dense clay 6. additional foundation pressure calculation of P 10. manhole pile load pre pressure method (B) to A. B. chemical grouting consolidation method C. compaction method D. vibrofloatation method Two, fill in the blanks (the title of 10 items, each item of 1 points, a total of 10 points) Please fill in the correct answer in each item in the blanks. The wrong, do not fill no points. 11. the preconsolidation pressure is greater than the soil cover existing gravity pressure soil called _ overconsolidated soil. 12. in general, the method of vertical bearing capacity of single pile is the most reliable to determine the static load test. 14. reinforcement of soft clay, often using sand drain preloading method, the main
