As urban expansion extends into complex mountainous regions,comprehensive engineering investigation of large-area mountainous sites faces multiple challenges, including insufficient investigation accuracy, failure to identify key geological problems, difficulties in integrating multiple standards,and a disconnect between investigation and design. Drawing on a large-scale comprehensive mountainous development project in Shenzhen,this study systematically analyzes the typical problems associated with technical methods,organizational coordination,and application of results at such sites.We propose and implement a data-driven, integrated digital solution: an integrated space–air–ground investigation technology that combines satellite remote sensing,UAV-based aerial surveying,ground-based geophysical exploration,and borehole drilling to achieve multi-source data fusion and accurate identification of geological bodies. On this basis,a refined three-dimensional geological information model(3D GIM) is constructed to support the entire project life cycle. Furthermore,a collaborative investigation–design mechanism that supports dynamic iteration is established,with this model as the shared digital foundation. Application results show that this solution substantially improves the efficiency and accuracy of geological exploration, supports differentiated design for earthwork balancing, foundation type selection, and slope treatment, and enables lossless transfer and value enhancement of geotechnical data. This approach provides a systematic technical pathway and methodological guidance for the investigation and construction of similar complex mountainous sites.

针对香港首个采用全组装合成建筑法（Full MiC）的项目——简约公屋SS M518的建造需求，围绕模块制造精度、多专业协同及关键部位防水等关键技术难题开展系统研究。在模块精度控制方面，研发了耦合器专用定位工装，将设计间隙2 mm条件下的连接偏差控制在2 mm以内。在多专业协同方面，引入AI智能设计平台与高精度BIM模型，实现自动深化出图与碰撞检测，相比传统设计模式，设计效率提升60%，并提前识别并修正了机电线槽支撑不足等问题。在屋面防水方面，集成“导排、防水、封堵、防护”复合构造，通过增设金属防护板、采用增强型防水涂层以及节点密封等措施，渗漏点数量减少90%以上。工程实践表明，所提技术措施有效保障了Full MiC全流程建造质量，可为同类项目提供技术参考。

In response to the construction requirements of Hong Kong's first Full Modular Integrated Construction(Full MiC) project—the Simplified Public Housing SS M518—systematic research was conducted on key technical challenges,including module manufacturing precision,multidisciplinary collaboration,and waterproofing of critical areas. For module precision control,a dedicated coupler positioning tool was developed,which controlled the connection deviation to within 2 mm under a designed gap of 2 mm. In terms of multidisciplinary collaboration, an AI-driven intelligent design platform and a high-precision BIM model were introduced, enabling automated detailed drawing generation and clash detection. Compared with traditional design methods,design efficiency was increased by 60%,and issues such as insufficient supports for mechanical and electrical cable trays were identified and rectified in advance. For roof waterproofing,an integrated composite system combining “drainage, waterproofing, sealing, and protection” was adopted. By adding metal protective sheets, applying enhanced waterproof coatings,and sealing critical joints,the number of leakage points was reduced by over 90%. Engineering practice demonstrates that the proposed measures effectively ensure construction quality throughout the entire Full MiC process and can serve as a technical reference for similar projects.

The Hong Kong Light Public Housing project SS M518 is he first project in Hong Kong to employ the Full MiC(full prefabricated steel modular integrated construction) method. The project faced several critical challenges, including high complexity in multi-disciplinary integration, stringent precision requirements for components, and low on-site module-hoisting efficiency. Focusing on the Yuen Long plot,the study integrates Building Information Modelling(BIM) with the Full MiC construction system. Standardised module decomposition and high-precision information models were developed,with a particular emphasis on the effectiveness of digital tools such as 3D laser scanning and layout robots in precision control, quality management, construction simulation, and schedule coordination. The practical results demonstrate the following:BIM-driven cross-disciplinary collaborative design identified and resolved 328 clashes among architectural,structural,and MEP disciplines,thereby eliminating on-site rework at the source. Model-driven CNC machining,combined with comprehensive 3D laser scanning inspection and real-time correction,raised the first-time factory acceptance rate of components to over 99.5%,and the installation errors of critical connections were consistently maintained within ±1 mm. By optimising the hoisting sequence and equipment scheduling through 4D construction simulation and Internet of Things(IoT) technology,the on-site hoisting efficiency improved by 25% compared with conventional methods. These results validate the significant advantages of integrating BIM with the Full MiC system in enhancing construction accuracy and efficiency,and they provide a technical reference for the large-scale deployment of similar high-density modular housing projects.

基于多孔介质多相流的主被动联合注浆数值模拟研究

Numerical Simulation Study of Main Passive Joint Grouting Based on Porous Medium Multiphase Flow

目前针对主被动联合注浆工况的注浆技术研究较少。以广东某盾构工作井井底注浆为背景，采用COMSOL软件分析注浆压力与基坑降水深度对浆液扩散的影响。结果表明：增大注浆压力、降低基坑降水深度可扩大浆液扩散范围并缩短注浆时间，但随注浆压力增大，降水深度的影响逐渐减弱。建议实际工程中适当提高注浆压力、降低降水深度以提升扩散效果。

At present,research on grouting technology under active–passive combined grouting remains limited. Using the bottom grouting of a shield working shaft in Guangdong as a case study, the influences of grouting pressure and foundation pit dewatering depth on grout diffusion were investigated with COMSOL Multiphysics. The results show that increasing grouting pressure and reducing dewatering depth can expand the grout diffusion range and shorten the grouting duration. However,the influence of dewatering depth gradually weakens as grouting pressure increases. Accordingly,properly increasing grouting pressure and reducing dewatering depth are recommended in practical engineering to improve grout diffusion.
