study on the microstructure feature and strength mechanism of the Tien Lake peat soil Yu Liu1, a, Guangzhu Cao2 and Yingui Meng,Mengxin Liu3 1,2Kunming University of Science and Technology,Yunnan,China 3GuiZhou University,GuiZhou,China Yunnan Construction Engineering Group,Yunnan,China a463046234@qq.com Keywords: Tien Lake peat soil, microstructure feature, material composition, strength mechanism.
Based on the mechanics test,microstructure detection means and component analysis test.We analyzed the microstructure, material composition and mechanical properties of Tien Lake peat soil.And we concluded the influence of microstructure on the strength mechanism.
in this field, is mostly about basic chemical and physical properties of peat soil and chemical elements of the environmental behavior.Mainly includes the following aspects:the study of physical and chemical properties of peat soil,the migration and transformation of special material in peat soil,peat soil biological filter and degradation of pollutants,the relationship of peatland with and environment,the application of peat soil.Research method is mostly adopts the combination of field investigation, measurement and laboratory simulation method.Therefore, the study of this paper has significant theoretical significance and practical value.In this paper,based on the mechanics test, combined with the microstructure detection and component analysis test,the author has studied the microstructure and material composition characteristics of Tien Lake peat soil, and so as the influence of mechanism to strength.
The Microstructure of Tien Lake Peat Soil To study microstructure and material composition of Tien lake peat soil,electron microscope scanning and energy spectrum analysis experiment has been carried out for it.

Problem Statement The construction industry consume a substantial amount of raw materials in the process.
The two major concerns on recycling are the economic viability and acceptability of recycled materials.
Typically, Tam and Tam (2005) found that from a purely economic point of view, recycled materials are only attractive when they are competitive with virgin materials in terms of cost and quality.
Interestingly, in contrast to a common sense, the cost of virgin material is actually cheaper than that of recycled materials (Tam and Tam, 2005).
Besides, the general public often worries about the quality of reused or recycled materials.

Therefore, these materials can be prepared into gas sensor array for detecting VOCS.
Gasochromic response of the above materials is not as significant as substitution of zinc porphyrin from this point of view.
It indicates that these materials have gasochromic characteristics while responding with organic gas.
Therefore, these materials can be prepared into gas sensor array for detecting Volatile Organic Compounds.
