Abstract
The deterioration depth (D) is a relatively simple index used to evaluate the deterioration degree of solidified soil. Based on the equivalent relationship between the accelerated deterioration tests and the conventional deterioration tests and the power function form of the D prediction equation, a rapid prediction method is proposed in this study for predicting the D of cement solidified marine soft soil. Deterioration test results of the cement solidified marine soft soil showed that increases in the concentration of seawater accelerated the rate of cement soil deterioration. Deterioration test results of the cement solidified marine soft soil showed that increases in the concentration of seawater accelerated the rate of cement soil deterioration. Additionally, the D obtained from indoor and in-site conventional deterioration tests is almost the same. A rapid prediction method for the D of cement stabilized marine soft soil was established with the equivalent relationship between the accelerated and conventional deterioration tests and a power function form of the deterioration depth prediction equation. The predicted D and the development trend were more consistent with the results of the indoor and in-site conventional deterioration tests.
劣化深度(D)是用于评价固化土劣化程度的一个相对简单的指标。根据加速劣化试验与常规劣化试验之间的等效关系以及 D 预测方程的幂函数形式,本研究提出了一种快速预测水泥固结海相软土 D 的方法。水泥土固化海洋软土的劣化试验结果表明,海水浓度的增加加快了水泥土的劣化速度。水泥固化海洋软土的劣化测试结果表明,海水浓度增加会加快水泥土壤的劣化速度。此外,室内和现场常规劣化试验得出的 D 值几乎相同。利用加速劣化试验和常规劣化试验之间的等效关系以及劣化深度预测方程的幂函数形式,建立了水泥稳定海相软土 D 的快速预测方法。预测的 D 值和发展趋势与室内和现场常规劣化试验的结果更加一致。
期刊介绍:
Soils and Foundations is one of the leading journals in the field of soil mechanics and geotechnical engineering. It is the official journal of the Japanese Geotechnical Society (JGS)., The journal publishes a variety of original research paper, technical reports, technical notes, as well as the state-of-the-art reports upon invitation by the Editor, in the fields of soil and rock mechanics, geotechnical engineering, and environmental geotechnics. Since the publication of Volume 1, No.1 issue in June 1960, Soils and Foundations will celebrate the 60th anniversary in the year of 2020.
Soils and Foundations welcomes theoretical as well as practical work associated with the aforementioned field(s). Case studies that describe the original and interdisciplinary work applicable to geotechnical engineering are particularly encouraged. Discussions to each of the published articles are also welcomed in order to provide an avenue in which opinions of peers may be fed back or exchanged. In providing latest expertise on a specific topic, one issue out of six per year on average was allocated to include selected papers from the International Symposia which were held in Japan as well as overseas.
