The specific embodiment
Below in conjunction with accompanying drawing illustrated embodiment, the present invention is further illustrated.
The invention discloses a kind of measuring method of Deformation of Diaphragm Wall, relate to in-site measurement and data processing two aspects.In-site measurement aspect, the present invention is using diaphragm wall 1 as scanning target, adopt three-dimensional laser scanning technique to measure, can obtain the three-dimensional coordinate of the measuring point that thousands of spacing are several millimeters, measuring speed is very fast, point cloud can be automatically recorded in the storage system of three-dimensional laser scanner, these coordinate datas can be derived in the data processing stage.The data processing stage puts cloud by diaphragm wall and is registrated in absolute coordinate system, and sets up the threedimensional model of diaphragm wall 1.Obtain after diaphragm wall surface profile by in-site measurement and data place technology, the diaphragm wall of different times 1 threedimensional model is compared, in threedimensional model, the change in location of character pair point is exactly the distortion of diaphragm wall 1 in this position, finally can obtain the bulk deformation information of foundation ditch.
As shown in Figure 1, when after the objective for implementation of the space enclosing structure of diaphragm wall 1 of determining a base pit engineering as diaphragm wall measuring method, the monitoring of its bulk deformation comprises the following steps:
(1) outside influence of foundation excavation region, be at least 3 reference points of boundary line, excavation influence area 6 outer layings 5, and before excavation, adopt the three-dimensional coordinate of control survey method datum mark 5 to set up absolute coordinate system; The working base point 4 of at least 3 deformation monitorings of boundary line, excavation influence area 6 interior layings in influence of foundation excavation region, when each issue deformation observation, working base point 4 and reference point 5 are carried out to translocation, to obtain the coordinate of working base point 4 in absolute coordinate system.
General, the scope in influence of foundation excavation region depends on character, excavation of foundation pit depth H, body of wall embedded depth, the lower sleeping soft layer degree of depth and the excavation Construction of Supporting method on stratum, in the present embodiment, influence of foundation excavation region is in the scope of outside, foundation ditch boundary line 1~4H.
As shown in Figure 2, because reference point 5 is positioned at outside influence of foundation excavation region, its position can not change, before excavation, determine the coordinate of reference point 5 by control survey method, at least three reference points 5 can form an absolute coordinate system, and now the three-dimensional coordinate of reference point 5 is known.Working base point 4 is positioned at influence of foundation excavation region, and its position can change in absolute coordinate system.When each issue deformation observation, working base point 4 and reference point 5 are carried out to translocation, the coordinate of surveying work basic point 4, just can determine the coordinate of working base point 4 in absolute coordinate system by the three-dimensional coordinate of known reference point 5.
Wherein, control survey method can be divided into two large classes, the first kind is vertical control survey and horizontal control survey, vertical control survey can adopt leveling measuring method, electromagnetic distance measurement Trigonometric Leveling, and horizontal control survey can adopt the methods such as triangulateration, traverse, GPS measurement and triangulation survey, trilateration survey.Equations of The Second Kind control survey method is three-dimensional control survey, can use the combined method of GPS measurement and triangulateration, traverse, measurement of the level and electromagnetic distance measurement trigonometric heighting.Translocation refers to by the known reference point 5 of coordinate measures the working base point 4 of coordinate the unknown, and concrete measuring method is identical with control survey.
In step (1), outside influence of foundation excavation region, by laying multiple prisms as reference point 5, the layout points position of reference point 5 is uniformly distributed and covers whole influence of foundation excavation region.Because each prism can be determined and the three-dimensional coordinate of a reference point 5 according to geometry principle, at least needs three reference points 5 can form a coordinate system, therefore in the present embodiment, the quantity of prism can not be less than 3.When actual measurement, number of prisms should be more than 4, and reason has two: 1. guarantee that part prism still can rely on remaining prism to form coordinate system while inefficacy; 2. unnecessary prism makes to measure and has redundancy, is conducive to improve certainty of measurement.But, if number of prisms is too much, can increase the workload of measurement, reduce measurement efficiency, also increase the cost of measuring.Based on above-mentioned consideration, in the present embodiment, 4 number of prisms are set altogether as reference point 5, but can take the circumstances into consideration to increase according to actual conditions.
In influence of foundation excavation region, the quantity of working base point 4 is quite a few in 3, and working base point 4 should be tried one's best near reference point and three-dimensional laser scanner survey station 3, so that measure simultaneously.The target at working base point 4 places and the prism of reference point 5 are without corresponding one by one, because the effect of working base point 4 is that the reference frame of the absolute coordinate system of reference point 5 and 3 D laser scanning is connected, according to the principle of coordinate transform, each working base point 4 at least will with two reference points 5 and two 3 D laser scanning survey station 3 intervisibility settings.In the present embodiment, consider with the layout of prism, in influence of foundation excavation region, lay 4 targets as working base point 4.
(2) adopt the laying mode of point standing posture to lay multiple survey stations 3 along the sideline of foundation ditch diaphragm wall 1 to arrange three-dimensional laser scanner, set up the reference frame of being determined by three-dimensional laser scanner, use three-dimensional laser scanner to obtain the some cloud of described working base point 4 and diaphragm wall 1, according to principle of coordinate transformation, three-dimensional coordinate using working base point 4 in absolute coordinate system is as benchmark, the point cloud of diaphragm wall 1 is converted into absolute coordinate system from reference frame, and deletes the noise spot except 1 cloud of diaphragm wall in absolute coordinate system.
Setting up absolute coordinate system according to the three-dimensional coordinate of reference point 5, and determine after the coordinate of multiple working base points 4 in absolute coordinate system, next adopt three-dimensional laser scanner to obtain the some cloud of working base point 4 coordinates and diaphragm wall 1 when each issue deformation observation, the coordinate of working base point 4 and 1 cloud of diaphragm wall is all in a reference frame of being determined by three-dimensional laser scanner, reference frame is specified by the built-in system of three-dimensional laser scanner, it is the initial point of coordinate system take the position at three-dimensional laser scanner place, in horizontal plane take certain two mutually perpendicular direction as x axle and y axle, take vertical direction as z axle.Because the coordinate of working base point 4 in absolute coordinate system and reference frame is all known, according to principle of coordinate transformation, the coordinate of working base point 4 is converted into absolute coordinate system from reference frame, and in this process, the some cloud of diaphragm wall 1 also can be converted into absolute coordinate system from reference frame.Measure and all carry out said process each time, just can make the some cloud of diaphragm wall 1 in same absolute coordinate system.
In step (2), when each issue deformation observation, on survey station 3, lay three-dimensional laser scanner, selected diaphragm wall 1 and working base point 4 carry out scanning survey as scanning target, each survey station 3 obtains the some cloud of a part of diaphragm wall 1, until the scanning at all survey stations 3 places all completes.In the time that each survey station 3 scans, at least to scan 3 working base points 4 and could meet the requirement of splicing.Meanwhile, sweep limits should cover whole diaphragm wall 1 in these survey station 3 visual line of sights.Certainly due to the blocking of actual sight line, each survey station 3 may can only scan a part of diaphragm wall 1, so multiple survey stations 3 need to be set, just can scan the whole diaphragm wall of foundation ditch 1.
Three-dimensional coordinate by working base point 4 in absolute coordinate system imports in some cloud the poster processing soft, as first group of data, import in some cloud the poster processing soft as second group of data with reference to the working base point 4 in coordinate system and 1 cloud of diaphragm wall, utilize the some cloud function in some cloud the poster processing soft to splice two groups of data, when splicing using working base point 4 as splicing control point, the frame of reference using the coordinate system of first group of data as splicing, is registrated in absolute coordinate system with the some cloud of diaphragm wall 1 the most at last; Then delete the noise spot except 1 cloud of diaphragm wall in absolute coordinate system; In order to obtain accurate diaphragm wall 1 threedimensional model, improve the reliability of measurement result, the some cloud frame selection tool in the present embodiment utilization point cloud the poster processing soft is chosen and is departed from diaphragm wall 1 point far away, is regarded as noise spot and deletes.
Above-mentioned some cloud the poster processing soft is any one in Cylone, Polyworks, Realworks Survey, Geomagic.
(3) according to the outline line of foundation ditch plan view, using the some cloud of the diaphragm wall of straightway 1 as a sector division out; And 1 cloud of the diaphragm wall of each section is divided into several regions, and the some cloud in each region is changed into a characteristic point, be used for representing the three-dimensional coordinate in this region, all characteristic points form the threedimensional model of diaphragm wall 1.
In step (3), the point cloud of diaphragm wall 1 is divided into the square net region of several 20cm × 20cm, to a coordinate system of some cloud definition in each region, making x axle is horizontal direction, z axle is vertical direction, and y axle is the normal direction of diaphragm wall 1, and the dimension of following provisions coordinate is m, if some cloud quantity is n in region, some cloud coordinate is:
p i=(x i,y i,z i),i=1,2,L?n
The border in region is determined by xmin and two parameters of zmin, meets following condition:
x min ≤ x i ≤ + 0.2 z min ≤ z i ≤ z min + 0.2 i = 1,2 , L n
The characteristic point p in this region *=(x *, y *, z *) can be determined by following formula:
x * = x min + 0.1 y * = 1 n Σ i = 1 n y i z * = z min + 0.1
If foundation ditch is rectangle as shown in drawings, diaphragm wall 1 can be divided into four planes, if foundation ditch is other shapes, is generally polygon, and diaphragm wall 1 will be divided into multiple planes
(4) diaphragm wall 1 threedimensional model of comparison different times, in threedimensional model, the displacement of character pair point is exactly the distortion of diaphragm wall 1 in this position.
The above-mentioned description to embodiment is can understand and use the present invention for ease of those skilled in the art.Person skilled in the art obviously can easily make various modifications to these embodiment, and General Principle described herein is applied in other embodiment and needn't passes through performing creative labour.Therefore, the invention is not restricted to above-described embodiment, those skilled in the art are according to announcement of the present invention, and not departing from the improvement that category of the present invention makes and revise all should be within protection scope of the present invention.
