An Annovative In Sita Testing SS-CPT Based Geotechnical Tomography/Technique for Soil Stratification

该项目提高了电磁地球物理断层扫描的技术水平，这是计算机轴向断层扫描（CAT）的一种改编，已成功用于医学诊断。以机械波为基础的地球物理断层扫描，已被用于研究边长达1000米的矩形区域，以及分析深层地球结构。资料来源包括气枪、炸药和地震数据。使用地震检波器（称为地震锥）来检测人工产生的波的到来，以确定地球物理特征，增强了该方法的能力。这种方法被称为震源锥贯入试验（SS-CPT）。然而，地震锥有几个限制。本研究提出了一种评估方法来解决这些限制。该实地评估将在加利福尼亚州记录良好的地点进行，那里已经进行了广泛的岩土工程调查，以建立现场分层。

This project enhances the state of the art in electromagnetic geophysical tomography, an adaptation of Computerized Axial Tomography (CAT) used successfully in medical diagnosis. Geophysical tomography, based on mechanical waves, has been used to study rectangular regions up to 1000 meters on a side, as well as to analyze deep earth structures. Sources have included airguns, explosives and earthquake data. The method's capabilities have been augmented using geophones, called seismic cones, to detect the arrival of artificially generated waves to determine geophysical characteristics. This approach is referred to as the seismic source cone penetration test (SS-CPT). However, the seismic cones have several limitations. This research proposes evaluation of a method to address these limitations. This field evaluation will take place at well documented sites in California where extensive geotechnical investigations have already been performed to establish site stratification.
