近年来,随着西部大开发、公路大建设的步伐,我省高等级公路的建设,在设计与施工方面也取得了很大的进步;采用先进的勘察、测量手段为公路路基设计提供了可靠的技术资料。作为公路主体工程的路基,公路路基综合稳定技术的,研制出了一大批用于路基工程的新材料:土工布、土工格栅、高强度塑料网、塑料排水板、加劲软式透水管、软硬塑料排水管、草坪植生带、轻质填料等材料;新型工程机械:大吨位振动压路机、加固土拌和机、塑料排水板插板机、土工布沉铺机、深层粉体搅拌成桩机;新技术、新方法:粉体搅拌法、塑料排水板法、锚固技术、喷锚支护、轻质路堤、网箱席垫、加筋技术,得到了充分的开发和引进,以及为这些新技术服务的各类专业化施工公司应运而生,专业化施工公司的建立和发展,为路基工程专项施工奠定了基础。现就本人在公路工程稳定路基技术方面的体会进行总结。
In recent years, along with the large-scale development of the western region and the pace of large-scale highway construction, the construction of high-grade highways in our province has made great progress in design and construction. The advanced survey and measurement methods have provided reliable and reliable roadbed design Technical information. As the main road project of roadbed and highway subgrade comprehensive stability technology, developed a large number of new materials for subgrade engineering: geotextiles, geogrids, high-strength plastic mesh, plastic drainage board, stiffened soft water pipes, soft Hard plastic drain, lawn vegetation belt, light stuffing and other materials; new construction machinery: large-tonnage vibratory roller, soil mixing machine, plastic drainage board flapper, geotextile disintegrator, deep powder mixing pile driver; New technologies and new methods: powder mixing method, plastic drainage board method, anchoring technology, spray anchor support, light embankment, cage mats, reinforcement technology, have been fully developed and introduced, and for these new technologies Services of various types of specialized construction companies came into being, the establishment and development of specialized construction company, laying a foundation for special construction of roadbed project. Now on my road engineering stability subgrade technology summary.
