Geological prospecting method applied to shallow-buried underground engineering in water-deficient area

Abstract

The invention provides a geological prospecting method applied to shallow-buried underground engineering in a water-deficient area. The geological prospecting method comprises the steps that geological prospecting is conducted, geological information of an engineering site is preliminarily obtained through remote sensing geological interpretation and engineering geological survey; comprehensive geophysical prospecting is carried out, and a small amount of drilling and logging work is carried out on key parts; in combination with an indoor rock-soil mechanics test, engineering geological condition comprehensive evaluation of an engineering site is obtained and comprises conventional stratum lithology, geological structure and surrounding rock classification, foundation bearing capacity anddynamic physical and mechanical parameters of a rock-soil body, and the parameters are used for engineering stability calculation of national defense engineering under the strong dynamic load condition. The investigation result meets the conventional requirements of shallow-buried underground engineering design construction, and meets the special purpose of national defense engineering. The geological prospecting method overcomes the defect that time and money are wasted when conventional prospecting mainly based on drilling is adopted, the prospecting cost is low, the efficiency is high, andthe geological prospecting method is more suitable for geological prospecting of shallow-buried underground engineering in arid and water-deficient areas.

Description

technical field [0001] The invention relates to the technical field of geological survey, in particular to a geological survey method applied to shallow buried underground engineering in water-deficient areas. Background technique [0002] With the rapid development of the national economy and the acceleration of national defense engineering construction, more and more underground space resources are being developed and utilized, making more and more shallow buried underground projects in some arid and water-deficient areas in the central and western regions, such as Air-raid shelters in the Gobi Desert, circular deep foundation pits, semi-underground aircraft hangars, etc. How to find out the engineering geological conditions of the site quickly and economically requires a comprehensive geological survey based on local conditions and the use of multiple technologies that cooperate with each other to verify.

Problems solved by technology

Due to the high time and economic costs of transporting water through the desert, the water transport trucks often face the risk of running aground in the desert, and the on-site work took at least 3 months (two drilling rigs work at the same time)
