场地韧性的概念及有关问题的讨论

在韧性城市和建筑抗震韧性等级评价中，需要对场地的韧性给出评价。场地韧性是一个新概念，场地韧性的概念和场地韧性等级评价在学术界还是空白。因此，对场地韧性的概念及有关问题开展讨论，对韧性城市和建筑抗震韧性评价具有重要的理论意义和工程应用价值。本文在分析韧性和场地概念的基础上，讨论了场地的稳定性和抗干扰问题；基于HOLLING建立的适应性循环理论，论述了建立场地韧性概念的理论基础；首次提出了场地韧性概念并解释了其内涵；考虑韧性城市和建筑抗震韧性评价的需求，初步讨论了与场地韧性等级评价有关的问题，提出了建立场地韧性等级评价指标体系的初步设想；建议了场地韧性等级评价的数学方法，为实现场地韧性等级评价提供了途径和方法。本文研究成果对从事韧性城市和建筑抗震韧性研究的科技工作者有一定的参考价值。

Concept of site resilience and discussion on relevant issues

It is necessary to evaluate the resilient of the site for classification and evaluation in resilient urban and seismic resilience of building. However,as a new concept,site resilience and how to evaluate it is blank space in academic circles. Therefore,research on site resilience has important theoretical significance and engineering application for resilient urban and seismic resilience of building. Based on concept of resilience and site,the stability and anti-interference of the site was discussed. From the adaptive cycle theory established by Holling,the theoretical basis for establishing the concept of site resilience was related and analyzed. The highlight of this paper,the concept of site resilience was proposed and interpreted for the first time. In order to consider the needs of seismic resilience evaluation of resilient urban and buildings,the problems related to site resilience grade evaluation were preliminarily discussed in this paper,and the preliminary idea of establishing site resilience grade evaluation indicators system was put forward. At last,the mathematical methods of site resilience grade evaluation were proposed,which providedthe methods for realizing grade evaluation of site resilience. The work of this paper has a certain reference value for relevant researchers.
