摘要
静力触探的发明和应用对于工程地质勘探和测试技术的发展具有里程碑的意义,静力触探目前已成为岩土工程行业原位测试中最基本的试验手段。文章概述了静力触探测试技术的发展历程,当前静力触探的新技术和发展方向,探讨了静力触探在以下方面的应用:进行土类判别和力学分层;确定土体结构和微地貌单元;确定土坡滑动界面;估算单桩承载力和沉桩阻力,确定粉细砂(粉)土桩端持力层的界线;确定地下人防和地下隐蔽物的位置;判断砂土液化以及配合钻探确定泥质软岩的中风化带界线等。
The invention and application of CPT is a milestone in the development of geological exploration and test technology, and currently CPT has become the most basic in-situ test means of geotechnical engineering. In this paper, the development course and new test techniques of CPT are described, and the applications of CPT are discussed,including differentiation and mechanical classification of soil, confirmation of soil structure and microgeomorphology, confirmation of the sliding interface of slopes, estimation of load capacity and sinking pile resistance, confirmation of the sideline of the supporting stratum at the pile-end in silt and fine sand（silty） soil, confirmation of underground civil defenses and underground objects, estimation of sandy soil liquefaction, and confirmation of the intermediary weathered sideline in soft clayey rocks in cooperation with field drilling.
