法国克莱蒙-费兰德布莱斯帕斯卡大学的R Gorves自1991年以来一直在设计和开发Panda，这是一种用于测试土壤和材料的轻型（20公斤）手持式动态锥形比重计。本文介绍Panda及其应用。Panda使用来自锤击的可变能量，可以由一个人操作，在几乎任何位置测试6米深的土壤。工具头部的加速计测量锤子的冲击速度，可伸缩的卷尺测量穿透深度。然后根据公式计算动态锥阻力和当前深度，并在计算机屏幕上真实的显示。Panda的多种应用可分为：（1）监测用于填土、挖沟工程、结构、开挖和覆盖以及地基改善的材料的压实情况;以及（2）所有类型的现场勘测。Panda软件中提供了一种简单的方法，用于在监测灌装时解释Panda测试的结果。文章介绍了使用这种方法的一些测试的结果，以及在几个测试台的网站，代表不同的土壤类型在英国的不同地区和开发的建筑研究机构（BRE）的结果。熊猫也可以用于地面改善作为一个纯粹的比较工具。
R Gorves at CUST, Blaise Pascal University, Clermont-Ferrand, France, has since 1991 designed and been developing the Panda, a light-weight (20kg) hand-held dynamic cone penetrometer for testing soils and materials. This article describes the Panda and its applications. The Panda uses variable energy from a hammer blow, and can be operated by one person to test soils to 6m deep in almost any location. An accelerometer at the head of the tool measures the hammer's speed of impact, and a retractable tape measures the penetration depth. The dynamic cone resistance and current depth are then calculated from a formula, and displayed in real time on a computer screen. The Panda's many applications can be classified into: (1) monitoring the compaction of materials used in fill, in trenching works, structures, cut and cover, and ground improvement; and (2) all types of site investigation. A simple method, available in the Panda software, interprets the results from a Panda test when monitoring fill. The article presents the results of some tests using this method, together with results at several test bed sites, representing various soil types in different parts of the UK and developed by the Building Research Establishment (BRE). The Panda can also be used for ground improvement as a purely comparative tool.
