动力触探(DPT)和动力圆锥贯入仪(DCP)试验在道路软基换填施工中的应用
Application of Dynamic Penetration (DPT) and Dynamic Cone Penetrometer (DCP) Test in Soft Foundation Dredging Construction of Roads

针对牙买加南部沿海路项目道路软基换填深度不明确及由于原地面在使用核子密度仪检测压实度受山区地形陡和原材料检测慢的问题，提出了用动力触探仪来测试路基基底的抗剪强度和用动力圆锥贯入仪测试路基原地面CBR来确定土体承载力，并介绍了荷兰动力触探仪和动力圆锥贯入仪的结构、使用方法、南部沿海项目应用成果整理，最终得出了路基清淤和原地面强度标准推荐值及路基清淤深度的确定方法。
Against Jamaica southern coastal highway project in road soft foundation filling replacement depth is not clear and the original ground using a nuclear density gauge test compaction due to steep mountain terrain and the problem of slow raw material testing, it is proposed with dynamic penetration testing (DPT) to test the shear strength of subgrade and use dynamic cone penetrometer (DCP) test roadbed original CBR to determine the bearing capacity of soil on the ground, and introduces the instrument and dynamic cone penetrometer structure, using method, results, and the application of results of a set of technical degree determination method. The method to determine the subgrade dredging depth and the recommended value of the original ground strength standard is proposed.
