无锡信息港淤泥质软土深基坑支护设计施工技术

Design and Construction of Deep Foundation Excavation Support in the Soft Soil Area of Wuxi teleport

无锡信息港项目根据周边环境的不同,选用桩锚支护和放坡土钉墙支护的无内支撑支护形式。为解决淤泥质土层和微承压含水层中常规土锚施工的难度,采用加筋水泥土锚桩与土钉墙的施工工艺,加强基坑边坡实时监测与控制,确保工程顺利进行,基坑施工的安全和周边环境的保护得到了有效控制。

Based on the different circumstances around Wuxi Teleport,the support method of pile-anchor retaining and soil nailing wall with step-slope are chosen.The reinforced cement anchorage pile and soil nailing wall are applied to solve the problem of construction difficulties at soft soil area and micro-pressure aquifer.The monitoring control are enhanced to ensure the construction schedule.The construction safety and surrounding circumstance protection are guaranteed effectively.
