摘要：复合土钉墙，作为土钉墙的进阶版支护结构，近年来备受瞩目。该技术融合了深层搅拌桩、旋喷桩、各类微型桩、钢管土钉及预应力锚杆等元素，并依据具体工程需求进行灵活组合，从而形成一种高效的复合基坑支护技术。它不仅克服了传统土钉墙的诸多局限，还有效拓宽了土钉墙技术的应用领域。复合土钉墙因其可靠性、经济性、高效性以及广泛的适用性，在工程中越来越受到青睐。本文以滨州医学院特教学生公寓的基坑支护项目为例，深入剖析了复合土钉墙支护技术的设计与施工流程，旨在为类似工程提供有益的参考。
Abstract: Composite soil nail wall, as an advanced support structure of soil nail wall, has attracted much attention in recent years. This technology integrates elements such as deep mixing piles, rotary jet grouting piles, various micro piles, steel pipe soil nails, and prestressed anchor rods, and can be flexibly combined according to specific engineering needs to form an efficient composite foundation pit support technology. It not only overcomes many limitations of traditional soil nail walls, but also effectively expands the application fields of soil nail wall technology. Composite soil nail walls are increasingly favored in engineering due to their reliability, economy, efficiency, and wide applicability. This article takes the foundation pit support project of the special education student apartment at Binzhou Medical College as an example to deeply analyze the design and construction process of composite soil nail wall support technology, aiming to provide useful reference for similar projects.
