Abstract

In this paper, we present a new framework for improving soil strength using an advanced method of engineering statistics. The materials included clay till collected in Yttre Ringvägen, southern Sweden. Binders included quicklime, slag and ordinary Portland cement used as pure binders and blended mixtures. We first applied the Response Surface Methodology techniques aimed at binder blend optimisation: 1) Central Composite Design; 2) Box-Behnken Design; 3) Simplex Lattice Design. The Pareto charts were presented for modelling responses from tests with different binders and estimating their effects on soil strength. Finally, to examine the variables important for soil stabilisation, we also evaluated the effect of the amount of binder and the interaction between cement/lime/slag in different ratios: 30-50-20 %; 50-50-0 %; 100-0-0 % The paper highlights the major opportunities and challenges of engineering statistics as a cross-cutting research direction for the issues of civil engineering.

利用帕累托效率和RSM调节Yttre粘土稳定中粘结剂含量Ringvägen, Malmö

在本文中，我们提出了一个新的框架，以提高土壤强度的一种先进的工程统计方法。这些材料包括在瑞典南部Yttre Ringvägen收集的粘土。粘结剂包括生石灰、矿渣和普通硅酸盐水泥，用作纯粘结剂和混合粘结剂。我们首先应用了响应面法技术，旨在优化粘合剂的混合:1)中心复合设计;2) Box-Behnken Design;单纯形点阵设计。提出了帕累托图，用于模拟不同粘结剂试验的响应，并估计其对土壤强度的影响。最后，为了检验对土壤稳定至关重要的变量，我们还评估了粘合剂用量的影响以及水泥/石灰/矿渣在不同比例下的相互作用:30-50- 20%;50-50-0 %;文章强调了工程统计作为土木工程问题的交叉研究方向所面临的主要机遇和挑战。

期刊介绍： Acta Polytechnica is a scientific journal published by CTU in Prague. The main title, Acta Polytechnica, is accompanied by the subtitle Journal of Advanced Engineering, which defines the scope of the journal more precisely - Acta Polytechnica covers a wide spectrum of engineering topics, physics and mathematics. Our aim is to be a high-quality multi-disciplinary journal publishing the results of basic research and also applied research. We place emphasis on the quality of all published papers. The journal should also serve as a bridge between basic research in natural sciences and applied research in all technical disciplines. The innovative research results published by young researchers or by postdoctoral fellows, and also the high-quality papers by researchers from the international scientific community, reflect the good position of CTU in the World University Rankings. We hope that you will ﬁnd our journal interesting, and that it will serve as a valuable source of scientiﬁc information.
