Under the background of accelerating new urbanization process, smart urban renewal has been transformed from “incremental construction” to “stock optimization”, and the traditional renewal mode is difficult to meet the demand of sustainable urban development due to data silos and lack of dynamic simulation. Based on digital twin technology, this paper explores the application path of smart urban renewal by constructing its technical framework, aiming to provide a full life cycle digital solution...

An architectural tour of our rural areas around the world showcases unique expressions of cultural identity through our buildings, spatial layouts, and decorations, often overshadowed in urban environments; Chad is no exception. Authors present their strategies for promoting local identities. In Chad, the architect-urban planner Senoussi Ahmat Senoussi oversees the women of Gaoui as they enhance their techniques in earthen decoration. Also, the architect ROGER Boriata studied the variation of tr...

The general layout of rail transit depots should be designed based on planning requirements, site constraints, and track connection conditions. It aims to ensure smooth and efficient train operation and maintenance while considering factors such as over-track property development and land use value. A comparative analysis of multiple schemes is essential. Taking a depot of a specific line in Shanghai’s rail transit system as an example, this paper proposes three layout schemes with varying posit...

In order to study the influence of time on the mechanical properties of red clay improved by plant fiber, the red clay in Guilin was taken as the research object. Three kinds of plant fibers, lignin, coir and ramie, were mixed into red clay respectively. The shear strength index and unconfined compressive strength of red clay improved by plant fibers at different curing ages were analyzed through indoor direct shear test and unconfined compressive strength test. The test results show that the sh...

In this study, gel-immobilized fillers were used to conduct partial nitrification experiments, including a small-scale experiment in the laboratory and a pilot experiment in a leather factory. The performance of the filler for partial nitrification was investigated by the small-scale experiment under the reactor start-up condition with low initial ammonia oxidizing bacteria (AOB) relative abundance. Then pilot experiment was carried out for the application of the filler in leather wastewater tre...

This study investigates the variations in shear strength parameters of red clay under different clay content and pH levels through direct shear tests. It analyzes the effects of normal stress, clay content, and pH on shear strength, cohesion, and the internal friction angle. The research reveals that with an increase in normal stress, the shear strength of the soil gradually increases under the same clay content and pH conditions. Under the same clay content, as the pH level becomes more acidic ...
