土壤中动植腐蝕物含量的多寡,从工程地質观点上来看是很重要的,因为这直接影响土的物理力学性質。550℃下的灼热損量,虽不能完全代表土內的有机質(因为有分子水及其它矿物揮發),但可以近似地表示出来,作为工程注意之一。今年第三季度,西安勘測队在为某一工程测定灼热損失时,因該項目的試驗数量多,操作方法陈旧,工作效率不高,每天都要积压一些,曾影响过整个土分析报告的提出。后来改进了操作方法,簡化了計算步驟,估計把原有工作效率提高了六倍多,从而速迅地完成了生产任务。
It is important from the engineering geological point of view that the amount of the plant-animal corrosion content in the soil is important because it directly affects the physico-mechanical properties of the soil. The burning loss at 550 ℃, though it can not completely represent the soil organic matter (due to the molecular water and other minerals volatilization), but can be approximated as one of the engineering considerations. In the third quarter of this year, when the Xi’an Survey Team measured the burning loss for a certain project, the project had a large number of tests, outdated operation methods and inefficient work, with a daily backlog which had affected the entire soil analysis report . Later, the method of operation was improved, the calculation steps were simplified, and it was estimated that the original work efficiency was increased more than sixfold to complete the production task quickly.
