Strength And Stability Factors Experimental Study Of TG Curing Agent Stabilized Soil

Solidified agent of soil is an admixture which mixed with the soil and the soil to a series of physical, chemical reaction, it can improve and enhance the engineering properties of soil, to ensure the quality, speed up the construction period, reduce the project cost. This paper is on the basis of the sandy soil and weathered sand two kinds of soil, with the composite stabilized soil of TG curing agent, lime, cement were studied.Firstly, by analyzing the engineering properties of the raw materials, then use the TG curing agent, cement and lime three kinds of curing materials as the influencing factors, their dosage as the factors and levels,7d unconfined compressive strength as the index, then orthogonal experimental design was carried out of stabilized soil, and according to the test results conduct the range and variance analysis. According to the results of orthogonal test, use the BP artificial neural network in MATLAB established the prediction model between TG curing agent stabilized soil and7d unconfined compressive strength, the results of orthogonal test were used to train the network model, then using the trained network to predict the strength of other mixture ratio, according to the prediction results, considering the factors of strength and economic etc., the optimum mixture ratio of two kinds of stabilized soil are TG curing agent:lime:cement:soil=0.02%:4%:4%:92%. On the basis of optimal mixture ratio, analysis the different levels and doses of cement,different calcium and magnesium concent and doses of lime,different doses of curing anent, different degree of compaction, health conditions, curing period and the percentage of moisture that effent on the the strength of stabilized soil,the stability of the water and temperature, flexural (splitting) strength, compressive modulus of resilience and the shrinkage performance of two kinds of stabilized soil were studied.
