湿陷性黄土边坡失稳及防治措施研究

兰州位于黄土高原的黄河河谷,随着城市的发展,建设用地非常紧张,各类建设向南北两山山坡、台塬等地质环境脆弱地带扩展,产生大量的开挖边坡和回填边坡。本文通过工程实例分析了湿陷性黄土边坡破坏的原因,提出湿陷性黄土边坡治理必须做好边坡排水设计和施工,将工程治理与工程治水相结合,加强后期管理对防止边坡失稳具有重要意义。

Collapsible Loess Slope Research and Prevention Measures

Collapsible loess water rational sensitive, dry very hard, can form upright in water soil slope after the decrease of strength, landslide, collapse to such geological disasters. Lanzhou is located in the loess plateau of the Yellow River valley. With the development of the city, the construction land is very nervous, all kinds of construction to the two mountain slopes, and Taiwan etc tableland geological environment vulnerability zones expand, have a lot of slope and backfilling slope. The slope, if not handled properly, will do great damage to the environment and engineering itself, even can cause huge economic losses and casualties. This article through the engineering examples analysis the cause of the collapsible loess slope destruction, proposes collapsible loess slope management must be prepared to slope drainage design and construction, projecting management and engineering with the combination of late, strengthening the management to prevent slope to have the important meaning.
