完备而可靠的工程地质资料是水工设计成败的关键 ,对工程结构安全、降低造价、保护环境 ,并对工程的施工与运行起决定性作用。提出了工程勘测研究优化问题。阐明了“积极设计”原理 ,应对施工及运行负载作用下地质环境的特征和状况改变进行预测性评估 ,对有关法规提出了修改建议。 Complete and reliable engineering geological data is the key to the success or failure of hydraulic design, which has a decisive effect on the structural safety of the project, the reduction of the cost, the protection of the environment and the construction and operation of the project. Proposed engineering survey research optimization problem. The principle of “positive design” is clarified, and the predictive assessment of the geological environment characteristics and conditions under the load of construction and operation should be carried out. Suggestions on the modification of relevant laws and regulations are proposed.
