Description
Technical field
The present invention relates to technical field of geotechnical investigation, more specifically to a kind of quick surveying method of Geotechnical Engineering.
Background technology
Any civil engineering is all closely related with ground, and they directly contact and interact with rock soil medium.Therefore, sufficient awareness and understanding are carried out for Rock And Soil distribution characteristics, engineering properties etc., is the important prerequisite for carrying out engineering design and construction.And it is then the Main Means for disclosing Rock And Soil spatial distribution (including distribution of the underground water closely related with Rock And Soil) and change to explore.
The form on all kinds of civil engineerings basis be it is different, have in " point " shape, have in " line " shape.The building construction of typical case's such as frame structure, structural column reaches on the ground of relatively independent point building gravity dispersion, now only needs to investigate the foundation soil property of each point, according to the basis of each point soil nature matter design structure；And the engineering such as subway, tunnel is distributed due to its continuity wire, the property of all soil of relevant position most preferably being understood, being design, work foundation is provided especially for construction.
Existing accurate geologic information is obtained by the probing of a position, and is put the geology distribution and point between and be difficult to or cannot understand, and this construction to linear engineering causes very big puzzlement.Such as the jacking construction and the shield-tunneling construction of subway engineering of water supply and sewage work, the unknown pipe network in underground, tree root, timber, ancient stream channel harbour etc. are frequently encountered, the large change of rock and soil properties is also for construction brings very big challenge.Therefore, wire engineering is highly desirable understands engineering completely continuous geology distribution.
The conventional method of geotechnical investigation has probing, probing and the class of geophysical exploration three.Probing is the direct method of engineering investigation, refer to manually or mechanical equivalent of light excavation prospect pit, exploratory trench, vertical shaft, adit etc..The method is limited by underground water, and cutting depth can not be too big, and difficulty of construction is big, and the engineering time is long.
Probing is the semi-direct method of engineering exploration, is one of topmost means of geotechnical engineering investigation.Compared with probing, geophysical exploration, probing has irreplaceable effect, different type, different structure, the building of different scales, structures, different phase of explorations, investigation and prospecting under the conditions of varying environment, typically all uses or part is explored using drilling method.Probing and probing are to understand geology of deep part data, find out the direct approach and reliable method of engineering geological condition.But labor intensive, material resources are more, it is necessary to the time is long.
It is applied to the geophysical exploration method referred to as engineering geophysics in geotechnical engineering investigation.It is the engineering geological condition of building yard, hydrogeologic condition, Characteristics of Geotechnical Engineering, bad geological phenomenon, dynamical stability to be explored using special geophysical instrument and special geophysical prospecting method and building yard wave speed of the earthquake is tested.The advantage of engineering geophysics is：Equipment is light, efficiency high, in ground, aerial, waterborne or drilling, (this is vertical drilling, different from horizontal drilling of the invention) in can carry out physical prospecting, according to research degree and precision and increasing exploration density, depth can be actually needed, realize the gauze of design exploration from different directions, multi-faceted data matrix is constituted, the characteristics of with volume rendering.But, engineering geophysical method often receives the interference of environmental factor and limiting to for Instrument measuring precision, and the result of its analysis is more rough.Therefore, engineering geophysics is usually the householder method of geotechnical engineering investigation.By the measuring method of the different physical field to geologic body, engineering geophysics can be divided into electrical prospecting, seismic prospecting, magnetic prospecting, gravimetric prospecting, radioactivity survey, well logging etc..
In a word, existing geotechnical investigation method has three classes, and probing therein, probing are direct methods, and form is the prospecting of " point " shape, and as a result apparent, engineering geophysics is indirect method, by the interference of environmental factor and limiting to for Instrument measuring precision, as a result roughly.
It is those skilled in that art's technical problem urgently to be resolved hurrily therefore, because there is above-mentioned technological deficiency in the prior art.
