摘　　要：生物酶固化剂作为一种绿色的土壤固化剂,由于其具有施工工艺简单、土体改良高效、经济效益好及环保等优点,而广泛应用于高速公路路基建设中。湖南省高速公路建设中,经常会遇到拟建高速公路经过高液限土区域,而高液限土体性能很难满足公路建设对路基土的要求。生物酶固化高液限土使得高液限土路基能够满足公路对路基土的强度要求,而在路基的使用过程中,环境水对路基土稳定性的影响这一问题不容忽视,路基土的水稳定性关乎高速公路的运营安全。本文针对生物酶固化路基土样的水稳定性试验,探究不同含量的生物酶的路基土饱和稳定性,为生物酶固化路基土的应用提供科学的依据。As a green soil curing agent,biological enzyme curing agent is widely used in expressway subgrade construction because of its simple construction process,high efficiency of soil improvement,good economic benefit and environmental protection.In the construction of expressway in Hunan province,it is often encountered that the proposed expressway passes through the area of high liquid limit soil,and the performance of high liquid limit soil is difficult to meet the requirements of highway construction for subgrade soil.Biological enzyme curing high liquid limit soil makes the high liquid limit soil subgrade meet the strength requirements of highway for subgrade soil.In the process of subgrade use,the impact of environmental water on subgrade soil stability can not be ignored.The water stability of subgrade soil is related to the operation safety of expressway.Aiming at the water stability test of biological enzyme solidified subgrade soil sample,this paper explores the saturation stability of subgrade soil with different content of biological enzyme,so as to provide a scientific basis for the application of biological enzyme solidified subgrade soil.
