Abstract

Recently, geotechnical studies have been conducted more progressively to utilize dredged soil. The inclusion of shredded rubber (SR) and natural minerals (NM) to stabilize dredged soil (DS) has become an exciting issue in the geotechnical field. This technique can be a promising environmental innovation for the future. This study aimed to investigate the unconfined compressive strength (UCS), California bearing ratio (CBR), and embankment performance under the strip footing test. The UCS sample was prepared using shredded rubber with a proportion of 2% and 3% and natural minerals with a proportion of 3%, 6%, 9%, and 12% from the dry weight of the soil. Whereas for the CBR samples (both in un-soaked and soaked conditions) were also prepared with a proportion of 2% and 3% shredded rubber and 6% and 9% natural minerals from the dry weight of the soil as well. The strip footing test was conducted in small-scale laboratory tests to evaluate the performance of stabilized dredged soil embankments. The applied load test was gradually increased until the embankment collapsed. The results showed that adding shredded rubber and natural minerals could increase the UCS value by 3–4 times and the CBR value by 2–3 times. Furthermore, 84% and 116% efficient results were obtained in the strip footing test for the 7 and 14 days of curing, respectively. Therefore, the utilization of dredged soil stabilized with SR and NM can be considered for use as a road foundation layer. Doi: 10.28991/CEJ-2023-09-05-016 Full Text: PDF

疏浚土-天然矿物稳定橡胶碎路堤路基路基性能研究

最近，岩土工程研究已逐步进行，以利用疏浚土。橡胶碎料与天然矿物的掺入稳定浚土已成为岩土工程领域的研究热点。这项技术在未来可能是一项很有前途的环保创新。本研究旨在探讨条形基础试验下的无侧限抗压强度(UCS)、加州承载比(CBR)和路堤性能。采用土壤干重中比例分别为2%和3%的碎橡胶和比例分别为3%、6%、9%和12%的天然矿物质制备UCS样品。而对于CBR样品(未浸水和浸水条件下)，也分别用2%和3%的碎橡胶和6%和9%的土壤干重天然矿物质制备。在小型室内试验中进行了条形基础试验，以评价稳定的疏浚土路堤的性能。加荷试验逐渐增加，直至路堤坍塌。结果表明，添加橡胶碎料和天然矿物可使UCS值提高3 ~ 4倍，CBR值提高2 ~ 3倍。在养护7天和14天的条形基础试验中，效率分别达到84%和116%。因此，可以考虑利用SR和NM稳定的疏浚土作为道路基础层。Doi: 10.28991/CEJ-2023-09-05-016全文:PDF
