冻胀量 meaning in Chinese
frost-heave capacity
Examples
- Study on the observation of delamination frost - heave amount
分层冻胀量的观测方法研究 - From experimental result , i preliminarily know that eps is good thermal insulation material because the absorption of water is low and heat insulation is good , it is practicable at preserving temperature field of frozen earth roadbed and bringing frozen disaster under control ; second , according to the analysis of the eps that is applied into practical project , i have studied the practical effect which eps preserve roadbed temperature field , and the influence that was made after building field . i have get that eps can influence moisture content and frozen upper limit , through practical measuring data , i have studied freezing and expanding quantity and melting and submerging quantity during a complete frozen and melting cycle as well as have expanded and proved the practical application effect of eps with some reference significance to deep research of some connected problems . finally , through computer data analysis , setting up the analytical model of finite unit , i have simulated the temperature field of roadbed heat preservation , then expounded and proved that the height of embankment influenced the effect of thermal insulation material
其一是对聚苯乙烯泡沫塑料( eps )保温板以及天然路基土层、路堤填料进行了室内试验分析，结合国内外现在的有关科研成果，综合确定其各项特征参数；从试验结果初步认识到聚苯乙烯泡沫塑料是一种吸水率低，隔热性好的保温材料，在冻土路基温度场的保护和冻害治理方面是可行的；其二通过eps保温板在现场工程实践中的应用分析，研究了保温板在保护路基土层温度场的实际效果以及修筑路堤后造成的影响，保温板对土体含水量、冻结上限的影响，通过实测资料，研究了在一个完整的冻融周期内整个路基的冻胀量和融沉变形量，论证了保温板的实际应用效果，对有关问题的进一步研究和相关工程设计具有参考意义；其三，通过计算机数值分析，建立有限元分析模型，对保温路基的温度场进行了模拟计算，论证了路堤高度对保温材料效果的影响。 - The test obsvervation include air temperature , ground temperature , foundation moisture , freeze depth , freeze capicity , freeze residual capicity , groundwater table and shape transform of canal lining , etc . throught systemic observation , analysis of impact about each factor on fundation freeze capicity , evaluate effect on anti freeze of various canal lining , comparison on technology and ecnomic of different method , a kind of main canal lining format is been recommended to engineering practice with siutable to ningxia local feature , fufilling the need of main canal safey i application , economic and practical , that is using polystyrene plate laying under concrete slate and grit taking replace of filling layer and optimizing design
试验观测内容包括气温、地温、基土含水量、冻深、冻胀量、冻胀剩余量、地下水位和砌体外观变化等项目。通过系统的观测，分析各因素对基土冻胀量的影响，评价各种衬砌型式的防冻西安理工大学工程硕士专业学位论文胀效果，并进行技术和经济综合分析比较，推荐出了适合我区特点、满足干渠安全运行、经济实用、防冻胀效果好的干渠防渗衬砌型式，即混凝土板下铺设聚苯乙烯板和砂砾石换填层结构型式，加以优化设计，用于工程实践。
