Summary

    A simple pile foundation to prevent wind damage was discussed in our first report. The present report proposes the design method of the simple pile foundation.
    The strength pararneters of the cohesive soil were presumed from the results of a Swedish weight sounding test, which is a simple investigative method. An analysis method of the beam on semi-infile and ideal elastic mediums was proposed for the estimation of the lateral bearing capacity of the pile. The pulling resistance of a pile was estimated based on the relation between side friction and N value of the soil. When the pulling resistance power was not satisfied, we proposed a method of setting up the well crib. It was set in the ground at a depth of about 0.5 m.
    Moreover, the design case of the pile foundation is described for the general two continuous greenhouses.
Keywords: design method of the pile foundation, frictional resistance, plastic greenhouse, coefficient of horizontal subgrade reaction, N value
