Evaluating liquefaction potential is essential for seismic micro-zonation for a specific area. Ground improvement of a site is conducted after the examination of the propensity of liquefaction of that site. The present study aims to evaluate the liquefaction potential and risk assessment for the world’s largest mobile manufacturing Plant in Noida city, which comes under Gautam Buddha Nagar district (U.P.), India, for different magnitudes of earthquakes, i.e., 7.5, 7.0, and peak ground acceleration (\(a_{\max }\) = 0.24 g). For this purpose, the factor of safety against liquefaction was evaluated at different depths from 32 boreholes and soil samples based on stress based approach derived from Idriss and Boulanger (Soil Dyn Earthq Eng 26:115–130, 2006) and the liquefaction potential risk index of the particular site was evaluated further. The results show that the study area is mainly comprised of silt and sand and falls under site class D (as per IBC International Code Council (2006) International building code (IBC). Washington, DC). The middle part of the study area shows high liquefaction potential. From the following analysis, 3D liquefaction potential risk models are prepared for classifying the boreholes from “very low” to “very high” (Iwasaki et al. in Proceedings of the 3rd international conference on microzonation, Seattle, vol 3, no 2, pp 1310–1330, 1982) along their depth. This rapid approach can be helpful for the future construction of earthquake-resilient structures and it may also help determine the risk of current underground structures like buried pipelines and metro railways, which are critical lifeline infrastructures of a city.

评估液化潜力对于特定区域的地震微区划至关重要。场地的地面改良是在检查该场地的液化倾向后进行的。本研究旨在评估位于印度 Gautam Buddha Nagar 区 (UP) 的诺伊达市世界上最大的移动制造工厂在不同震级（即 7.5 级、7.0 级和峰值）的情况下的液化潜力和风险评估。地面加速度（\(a_{\max }\)  = 0.24 g）。为此，根据 Idriss 和 Boulanger (Soil Dyn Earthq Eng 26:115–130, 2006) 导出的基于应力的方法以及液化潜在风险指数，对 32 个钻孔和土壤样本的不同深度的液化安全系数进行了评估对特定地点进行了进一步评估。结果表明，研究区域主要由淤泥和沙子组成，属于 D 级场地（根据 IBC 国际规范委员会 (2006) 国际建筑规范 (IBC)。华盛顿特区）。研究区中部显示出较高的液化潜力。根据以下分析，准备了 3D 液化潜在风险模型，用于将钻孔从“非常低”分类到“非常高”（Iwasaki 等人，《第三届微区划国际会议论文集》，西雅图，第 3 卷，第 2 期，第1310–1330, 1982）沿着他们的深度。这种快速方法有助于未来抗震结构的建设，也可能有助于确定当前地下结构（如埋地管道和地铁铁路）的风险，这些结构是城市的重要生命线基础设施。
