发布时间：2018-07-13 07:45
【摘要】：土壤固化剂是一种新型固化类材料，具有施工简单、就地取材的特点，因此被广泛应用于各类固化土体工程，其经济效益和社会效益比较显著。本文以神木县通村公路工程为依托，研究了SG-1型土壤固化剂稳定碎石土在低等级道路基层中的应用。 论文分析了SG-1型土壤固化剂和碎石土的性质，通过室内击实试验和7d无侧限抗压强度试验研究SG-1型土壤固化剂稳定碎石土的配合比设计。设计了延迟试验研究SG-1型土壤固化剂稳定碎石土的强度随成型时间的变化规律。在施工过程中，SG-1型土壤固化剂稳定碎石土的含水量受到各种因素的影响，蒸发和土壤固化剂水化导致其水分散失，含水量下降，为此，本文设计了水化模拟试验，并提出蒸发公式，对含水量进行控制。在对SG-1型土壤固化剂的组分分析基础上，本文用EDTA滴定试验检测SG-1型土壤固化剂稳定碎石土中固化剂剂量，，并分析了测定时间、含水量和取样方法对EDTA滴定试验结果的影响。 通过试验段的铺筑和质量检测，本文研究了SG-1型土壤固化剂稳定碎石土的施工方法。最后，在室内试验研究的基础上，并结合实体工程，本文对SG-1型土壤固化剂稳定碎石土在施工过程中的含水量控制和土壤固化剂剂量控制进行了实际验证，证明了控制方法的可行性。
[Abstract]:Soil curing agent is a kind of new kind of curing material , it has the characteristics of simple construction and material , so it is widely used in various kinds of solidified soil engineering , its economic benefit and social benefit are remarkable . The application of SG - 1 soil curing agent stabilized crushed stone soil in low grade road base course is studied based on the highway engineering of Shenmu County .
In this paper , the properties of SG - 1 soil curing agent and crushed stone soil are analyzed . The effect of SG - 1 type soil curing agent stabilized crushed stone soil is studied by indoor compaction test and 7d without side - limit compressive strength test . In the course of construction , the water content of stabilized crushed stone soil of SG - 1 type soil curing agent is influenced by various factors .
In this paper , the construction method of stabilized crushed stone soil for SG - 1 soil curing agent is studied through the paving and quality detection of the test section . Finally , the water content control and the control of the dosage of the soil curing agent in the construction process of the SG - 1 soil curing agent stabilized crushed stone soil are verified by the laboratory tests , and the feasibility of the control method is proved .
