摘要：深圳市盐田支线引水工程旨在弥补盐田区水量不足，实现双水源供水，以提升供水稳定性和抗风险能力。该工程地质条件多变，需灵活应对。本文根据地质差异采用不同施工与支护策略，特别是爆破参数的优化，成为提升施工效率的关键。同时，项目还运用“新奥法”技术，并辅以常规围岩量测技术，确保了施工安全与速度。通过这些高效且实用的施工技术，本项目实现了成本节约与工期保障，为同类中小型隧道工程提供了宝贵经验。
Abstract: The Yantian Branch Water Diversion Project in Shenzhen aims to make up for the insufficient water supply in Yantian District, achieve dual water source water supply, and enhance water supply stability and risk resistance. The geological conditions of this project are varied and require flexible response. This article adopts different construction and support strategies based on geological differences, especially the optimization of blasting parameters, which has become the key to improving construction efficiency. At the same time, the project also utilizes the "New Austrian Method" technology, supplemented by conventional rock measurement techniques, to ensure construction safety and speed. Through these efficient and practical construction techniques, this project has achieved cost savings and schedule guarantees, providing valuable experience for similar small and medium-sized tunnel projects.
