水土保持设施验收是输变电工程水土保持工作的重要组成部分,在自主验收新形势下有许多要点和难点有待探讨.结合相关文件及输变电工程水土保持设施验收实践,总结了输变电工程的水土保持特征、水土保持设施验收程序和要求,从验收调查(资料收集、现场核查、公众调查)、组织验收(水土流失防治分区验收、水土流失防治责任范围验收、水土保持措施及效果验收、水土保持工程质量验收、水土保持投资验收、水土保持管理验收)、验收公示、验收报备等方面分析讨论了输变电工程水土保持设施验收工作的技术要点.在自主验收大背景下,提出了做好水土保持全过程管理、严格做好水土保持设施验收、做好水土保持设施后期管理维护、加大水土保持监督管理力度等建议,以期为建设单位和相关从业人员提供借鉴,提高输变电工程水土保持设施验收工作的质量和效率.

Relying on power transmission and transformation project,a laboratory experiment was conducted to study the curing effectiveness of high strength and water stability earth consolidator(HEC) soil stabilizer applied to three typical soils in the Gobi Desert region.The influence factors for the curing effectiveness such as curing age and curing agent content were analyzed at the 1.5 MPa unconfined compressive strength.Results from the laboratory tests show that the curing effectiveness of the three soils meets design requirements when curing period is more than 7 days and hardener volume reaches 8% and above.The tests for mechanical properties,permeability performance and shrinkage performance indicate that all the performances of samples meet soil and water conservation requirements in transmission line project.

The paper introduces effective teaching of biochemical waste water treatment process.Teaching of funda- mental theory knowledge with clear presentation,network propagation and visualization makes teaching more close to practical production so as to raise knowledge level and operation ability of first-line operators.
