中新网沈阳9月30日电 (王翕瞳)京哈高速盘锦至沈阳段改扩建工程软基处理、风积沙路基拼宽试验段9月30日开工,标志着京哈高速盘锦至沈阳段改扩建工程正式启动。

京哈高速盘锦至沈阳段改扩建项目起自盘锦枢纽互通式立交,止于沈阳西收费站,途经盘锦市盘山县,鞍山市台安县,沈阳市辽中区、铁西区、新民市、于洪区,全长129.52公里,估算投资139亿元。项目建成后将进一步提升京哈走廊通行效率和服务水平,缓解既有道路通行压力,强化沈阳与沿线城市联系,降低物流成本,带动沿线产业和旅游发展,对落实东北全面振兴国家战略、支撑沈阳现代化都市圈建设具有重要意义。

本次先行启动的试验段涵盖风积沙路基试验路与软基处理试验路两类,旨在为后续全线设计、施工提供关键技术支撑。沈盘高速全线约99公里路基为风积沙填筑,改扩建拼宽施工中原路基稳定性、新旧路基沉降差直接关系保通运营安全与工程质量。

试验段建设聚焦五大目标:一是验证拼宽路基就地固化工艺可行性,破解新旧路基拼接沉降差、开裂、滑移等常见病害;二是检验各类设备适配程度,确定标准化施工参数;三是优化机械组合、工序及人员配置,排查施工隐患,统一全线工艺与质量标准;四是校验检测指标,建立适配本项目的验收标准,保障新旧路基整体性、稳定性。五是验证施工扬尘、噪声等环保防控措施落地效果,进一步提升环评报告的科学性、精准性和实操性。试验段工期为2026年9月30日至2027年5月31日。

据介绍,本项目是在保通状态下风积沙路基拼宽施工。在既有道路正常通行的前提下,科学组织交通导改与施工工序,采取放缓削坡坡率、设置倾斜式台阶、坡面水泥砂浆封护等措施,确保旧路边坡稳定,实现“边通车、边扩建”。

同时,辽宁省内首次应用浅层软基就地固化技术,率先在省内高速公路建设中引入就地固化技术,原位固化土层,显著提高地基承载力与稳定性;避免传统换挖换填,减少材料运输与环境污染,施工速度快、成本可控、绿色环保。

软基处理全过程智慧化管理,全面引入智慧化管理系统,依托物联网传感设备对软基处理全过程实时监测、数据采集与智能分析,动态掌握质量、进度、安全状况,实现"可视、可溯、可控"的精细化管理目标。

辽宁省交通运输厅公路处处长石健介绍,京哈高速公路是《国家公路网规划》中七条首都放射线之一,是东北地区交通运输的大动脉和进出关的重要通道。

20 years of waiting! Provincial Route 76 from Caotun to Fangyuan is open to traffic, saving 20 minutes on the journey

The 20.8-kilometer west extension of Provincial Highway 76 (Caotun-Fangyuan) was completed and opened to traffic at 12 noon on the 8th. It starts from the Fangyuan Interchange of Provincial Highway 61 in the west, connects Erlin and Puyan in the east, and connects to the existing Provincial Highway 76, connecting Provincial Highway 61, National Highway 1 and National Highway 3. The journey from Caotun to Fong Yuan is shortened from about 55 minutes to 35 minutes, saving about 20 minutes. Chief Executive Officer Zhuo Rongtai pointed out that this section directly connects Fangyuan Industrial Zone, Erlin Zhongke Base and Precision Park, improving the core capacity of the central precision smart park, and has disaster relief and medical referral functions. The project adopts a sponge road design, which combines flood detention and landscape green corridors, and integrates human-oriented environment and bicycle paths. The planning of this road section can be traced back to the "National Six-Year Economic Construction Plan" in 1991. In 2018, the extension project was approved by then Executive President Lai Ching-te and took about 20 years to complete.
