Compaction Induced Lateral Earth Pressures

本研究的目的是探讨压实土引起的侧向土压力大小的控制因素。该项目将包括实验室测试，以调查压实方法、压实力、干密度和水分含量对压实引起的土压力大小的影响。试验将在模型试验箱中进行，并在分层压实土中进行；将测量产生的侧向压力。这些测试将提供一种方法来研究压力随轧辊移动方向的变化，并将为在严格控制的条件下评估可用的分析技术的有效性提供基础。这项工作将对基本的岩土工程过程采取基本的方法，并将广泛使用一种新型仪器--温度补偿水银固结仪。

The objective of this research is to investigate the factors controlling the magnitudes of the lateral earth pressures induced by compacting soil. The project will include laboratory tests to investigate the effects of compaction method, compactive effort, dry density, and water content on the magnitudes of compaction induced earth pressures. Tests will be conducted in a model test bin and in compacting soils in layers; the induced lateral pressures will be measured. These tests will provide a means of studying variations in pressures depending on the direction of roller travel and will provide a basis for assessing the effectiveness of available analytical techniques under carefully controlled conditions. This effort will take a fundamental approach to a basic geotechnical engineering process and will extensively use a new type of instrumentation, the temperature compensated mercury oedometer.
