摘要
通过同时使用3支底部开口大小不同的CO_2快速测定管在同一测定孔观测断层土壤气CO_2含量的实验,研究快速测定管开口大小对CO_2含量测值的影响及变化特征。结果表明,快速测定管底部开口大小不同,CO_2含量测值有显著差异;CO_2含量数据在变化形态方面有较好的同步性,观测结果呈夏高冬低的特点;与测定孔内的温度有显著的正相关关系。建议观测时,要注意快速测定管底部开口位置的一致性、温度等因素的影响。
Influence of opening size of rapid determination tube on CO 2 content and the variation characteristics are studied by detec‐ting CO2 content of fault soil gas in the same observation hole using 3 rapid determination tubes with different bottom openings sizes . The results show that different sizes of bottom openings of rapid determination tubes get significant difference CO 2 content values ;The CO2 content data have good synchronization in change form and the observation results show the characteristics of low in summer and high in winter ;There is a significant positive correlation with the temperature inside the observation hole .We should pay atten‐tion to the influence of position consistency of bottom opening of the tube ,temperature and other factors in observation .
