本文利用千叶市和千叶县西北部地区的PS测井结果，估算了地表的S波速度。该区由洪积层、冲积层和充填土组成。在回归分析的基础上，给出了砂性土和粘性土的SPTN值和深度的S波速度表达式，以及腐殖质土(泥炭)和关东壤土的S波速度标准值。
In this paper, the results of PS-logging conducted in Chiba city and the northwest area of Chiba prefecture are used to estimate S-wave velocity of the surface ground. This area consists of diluvial formation, alluvium and filling soil. Based on the regression analysis, expressions that give S-wave velocities of sandy soils and cohesive soils from SPT N-values and depth are proposed, as well as standard values of S-wave velocities for humic soil(peat) and Kanto loam.
