静力触探在福州市工程地质勘察中的应用研究

静力触探作为工程地质勘察的重要辅助手段,它能很好地表征与再现地层结构及物理力学性状在剖面上的变化和差异特性。静力触探曲线的形态特征、分布相对位置、特征参数(?)(?)及(?)的数值等与土质的种类、物理力学性状指标有密切的关系。本文在归纳分析和研究大量现有福州地区的静力触探资料及与其相关的地质资料的基础上,提出了利用静力触探成果资料划分与命名福州地区常见土层的综合标准,并给出了定量推算评价各相关土层的物理及力学特性指标的相关经验方程式。

Application of the Static Sounding in the Enginerring Geological Investigation in the Fuzhou Area of Fujian Province

This paper focuses on the application of the static sounding in the enginerring geological investigation in the Fuzhou area of Fujian Province. The shape features and distribution of the static sounding curves and values of the characteristic parameters q_c, f_s and R_f have a close relationship with the soil types and physiomechanic features. Based on the analysis of the static souding data and related geological information in the Fuzhou area of Fujian Province, the author presents in the paper a synthetic standard of classification and naming of Quaternary soil layers in the Fuzhou area, and gives the experienced formulas of appreciating quantitatively the physical and mechanic properties of individual correlative soil layers in the Fuzhou area.
