Cone Penetrometer Testing (CPT)

静力触探试验(CPT)是以静压力将圆锥形探头按一定速率匀速压入土中, 量测其贯入阻力(包括锥头阻力和侧壁摩阻力或摩阻比), 并按其所受阻力的大小划分土层, 确定土的工程性质。静力触探试验能确定各类土体的空间分布及其工程特性, 且野外现场作业简单、方便、测试时间短, 在工程地质勘察中得到广泛应用。

* Faster and generally cheaper than drilling and sampling * more consistent and reliable results than Standard Penetration Test (SPT) * usually used as initial investigation and further followed by drilling and sampling after analyzing CPT results

GIS-based Hydraulic modeling software

Upgrade included:

Full GIS Integration – Instead of a using static import of GIS info to create a model, the user can now use the Info products’ more powerful GIS Gateway tool that makes updating and creating models much faster and more transparent. In addition, users can use a raster with elevations to extract any data that might help make the model more accurate.

More powerful maps – Whether using ESRI basemaps that are built-in the software or creating thematic mapping for model results, the Info products are more versatile but offer a familiar feel. For example, nearly every icon in H2OMAP is identical to the ones used in the ESRI based products, making it incredibly easy to learn.

Easier navigation – Simple scrolling the mouse wheel to zoom in and out and clicking and holding the mouse wheel to pan is a huge time saver for existing users of the Esri-based products.
