Abstract

Subways, underground logistics systems and underground parking, as the primary facilities types of underground, contribute significantly to the achievement of carbon–neutral cities by moving surface transportation to underground, thereby releasing surface space for the creation of more urban blue-green space for carbon sink. Therefore, in-depth studies on carbon neutrality strategies as well as reliable layout optimization solutions of these three types of underground facilities are required. This study proposes a spatial layout optimization strategy for carbon neutrality using underground hydrogen storage and geothermal energy for these three types of underground facilities employing a multi-agent system model. First, three spatial layout relationships, competition, coordination, and followership, between five underground facilities that contribute to emission reduction were investigated. Second, the implementation steps for optimizing the spatial layout of underground facilities were determined by defining the behavioral guidelines for spatial environment, underground facility, and synergistic agent. Finally, using the Tianfu New District in Chengdu City, China, as a case study, layouts of underground facilities under three different underground space development scenarios were simulated to verify the model. The findings of this study address the gap in the research on underground spatial facilities and their layout optimization in response to emission reduction. This study provided a significant reference for the study of underground space and underground resources at the planning level to aid in achieving carbon–neutral cities.

优化地下设施空间布局,实现城市碳中和:多代理系统模型
地铁、地下物流系统和地下停车场作为地下的主要设施类型,通过将地面交通转移到地下,从而释放地面空间,创造更多的城市蓝绿碳汇空间,为实现碳中和城市做出了重要贡献。因此,需要对这三类地下设施的碳中和策略以及可靠的布局优化方案进行深入研究。本研究采用多代理系统模型,针对这三类地下设施,提出了利用地下储氢和地热能实现碳中和的空间布局优化策略。首先,研究了有助于减排的五种地下设施之间的竞争、协调和追随三种空间布局关系。其次,通过定义空间环境、地下设施和协同代理的行为准则,确定了优化地下设施空间布局的实施步骤。最后,以中国成都市天府新区为例,模拟了三种不同地下空间发展情景下的地下设施布局,以验证模型的有效性。该研究成果填补了地下空间设施及其布局优化研究在减排方面的空白。该研究为规划层面的地下空间和地下资源研究提供了重要参考,有助于实现碳中和城市。

期刊介绍: Underground Space is an open access international journal without article processing charges (APC) committed to serving as a scientific forum for researchers and practitioners in the field of underground engineering. The journal welcomes manuscripts that deal with original theories, methods, technologies, and important applications throughout the life-cycle of underground projects, including planning, design, operation and maintenance, disaster prevention, and demolition. The journal is particularly interested in manuscripts related to the latest development of smart underground engineering from the perspectives of resilience, resources saving, environmental friendliness, humanity, and artificial intelligence. The manuscripts are expected to have significant innovation and potential impact in the field of underground engineering, and should have clear association with or application in underground projects.
