It is difficult to evaluate soft foundation treatment technology using the traditional mathematical approaches, because there are not only quantitative factors but also qualitative factors which affecting the evaluation result. To analyze the non-quantitative problems and make the complicated technology assessment simple, multi-level synthetic fuzzy evaluation is utilized and numerical examples of national defense highway construction show the model is appropriate.

In this paper, we sorted soft foundation treatment technology by quantifying based on evaluation technique of life cycle environmental load and choose cement mixing pile which life-cycle environmental load is small and spiral pump pressure CFG pile which carrying capacity is high to integrate. It not only improved soil compaction effects, but also solved the problems of other technologies in the foundation process, such as low carrying capacity, reduced diameter, broken pile, virtual pile and so on. Besides, it has reduced the cost of the project and the application prospects are broad.

As a new ground treatment technology, the bag-grouting-pile composite foundation is used in railway soft soil reinforcement. In this paper, the application effect of bag-grouting-pile in coastal soft foundation treatment was studied in this experimental research; the deep settlement and the deep horizontal displacement of embankment edge in bag-grouting-pile composite foundation are tested in the research. The results of research show that the bag-grouting-pile composite foundation is a cost-effective ground treatment technology using in coastal soft foundation treatment.

In recent years, nature-based solutions have been increasingly promoted as a climate change adaptation instrument, strongly advocated to be co-created. Achieving clear, coherent, and ambitious urban greening strategies, embedded in urban planning and developed in a co-creative, participatory and inclusive manner, is highly challenging within the EU enlargement context. In this article, such challenges are studied through two recent urban development initiatives in Belgrade, the Capital of Serbia: the first initiative focuses on planning the new Linear Park, within the framework of the CLEVER Cities Horizon 2020 project; the second initiative envisages the transformation of the privatised Avala Film Complex in the Košutnjak Urban Forest, primarily led by private interests but supported by the local authorities. The multiple-case study research method is applied, with an exploratory purpose and as a basis for potential future research on evaluation of co-creation processes for NBS implementation. The theoretical basis of this article is founded in the research on sustainability transitions, focusing on multi-level perspective (MLP) framework. The urban planning system in Belgrade and Serbia is observed as a socio-technical regime of the MLP. In such framework, we recognize co-creative planning of the Linear Park as a niche innovation. We interpret opposition towards planning of the Avala Film Complex as escalation, or an extreme element of the socio-technical landscape, comprised of civic unrests and political tensions on one side, combined with the climate crisis and excessive pollution on the other side. Moreover, the article examines informal urban planning instruments that can be implemented by the practitioners of niche innovations, that could support urban planners and NBS advocates in the Serbian and EU enlargement contexts to face the challenges of motivating all stakeholders to proactively, constructively and appropriately engage in co-creation.
