Abstract

The study is to design field-operated plate load test equipment to overcome the problem of predicting bearing capacity and settlement of clayey soil on site using the conventional/traditional methods of short-duration plate load test where a hydraulic jack is used in conducting the test. Ashby's method of material selection was used for the selection of a suitable material for each of the components. The 12 mm thickness was obtained as the minimum safe thickness for the applied load of 500 kg on the lever arm. The I-section frame that support the entire system has sectional modulus of 19.4 cm3 and 4 mm thickness. The equipment will use a lever arm mechanism to conduct an in-situ test that will take long-duration on clay soil where the dissipation of pore water from the clayey soils takes a longer time to complete as against the current conventional method of plate load test that is in use. The equipment will offer several advantages in terms of cost, reliability, portability, authenticity, and user friendly.
现场板载试验装置的结构设计,以确定粘土的原位承载力和沉降
本研究旨在设计现场操作的板载试验设备,以克服使用传统/传统的短时间板载试验方法在现场预测粘性土的承载力和沉降的问题,并采用液压千斤顶进行试验。阿什比的材料选择方法用于为每个组件选择合适的材料。12毫米的厚度是杠杆臂上施加500公斤载荷时的最小安全厚度。支撑整个系统的工字钢框架的截面模量为19.4 cm3,厚度为4 mm。该设备将使用杠杆臂机构进行现场测试,该测试将在粘土上进行,与目前使用的传统板载测试方法相比,粘土中孔隙水的耗散需要更长的时间才能完成。该设备将在成本、可靠性、便携性、真实性和用户友好性方面提供几个优势。
