一、前言利用静力触探资料确定土的有关物理力学性质指标,国内外已取得很多成果,并已逐步推广应用;而对划分土的种类问题,目前尚未得到令人满意的结果。为此,我们对北京、天津、石家庄及南京、上海等地区的70个触探孔及其相应的钻孔资料(共270组土层,包括软土、一般粘性土、砂土),进 I. INTRODUCTION The determination of relevant physical and mechanical properties of soil using static penetrating data has yielded many achievements both at home and abroad, and it has been gradually applied. However, satisfactory results have not yet been obtained for the classification of soil types. For this purpose, we have included 70 contact holes and their corresponding borehole data (a total of 270 soil layers, including soft soil, general cohesive soil, and sand soil) in Beijing, Tianjin, Shijiazhuang, and Nanjing and Shanghai.
