Background
In the extension structure area, a large number of shovel-type normal faults develop, the upper disc of the general shovel-type normal faults develops rolling anticline, and a certain relation exists between the fault plane form of the shovel-type normal faults and the geometric form of the upper disc rolling anticline, and the relation is the basis of extension fault sunken basin structure balance analysis.
The principle of layer length conservation is one of deformation mechanisms of disc rolling anticline on a shovel fault, and essentially means that the length of a disc stratum on a main fault is kept constant before and after deformation, namely, as shown in fig. 1, the length of a line segment aL is equal to the length of a line segment a' L. Therefore, based on the principle and according to the parallelogram rule, the sectional surface form of the shovel type normal fault is described by combining the position of the upper disc rolling back-oblique geometric form surface of the shovel type normal fault, or the upper disc rolling back-oblique geometric form surface of the shovel type normal fault is described by combining the position of the sectional surface of the shovel type normal fault, wherein the sectional surface refers to the rolling back-oblique geometric form surface of the shovel type normal fault.
Specifically, as shown in fig. 1, the method for determining the cross-sectional geometry by using the known disk rolling anticline geometry on the shovel type forward fault specifically comprises the following steps:
(1) the region reference line aL is made such that aL ═ a' L.
(2) A perpendicular line a' b is drawn on the region reference line.
(3) Starting from the point a ', cutting a line segment on the layer surface to enable a' b 'to be ab, intersecting the layer surface at the point b', translating the line segment bb 'along the perpendicular line a' b to intersect at the point a ', and obtaining a translation line a' a1Finally obtaining the parallelogram a 'bb' a1。
(4) Making a perpendicular line of the area datum line through the point b', crossing the point c, and repeating the operation of the step (3) to obtain a translation line a1a2。
(5) Analogizing in turn to respectively obtain translation lines a2a3，a3a4……。
(6) And connecting the obtained series of translation lines end to complete the fault track.
The method for determining the upper disk rolling anticline geometry of the shovel type normal fault by using the known cross section shape of the shovel type normal fault is opposite to the method.

Wherein, the lower extreme of arc section 2 is tangent with the bottom of cuboid box. It should be noted that the heights of the arc-shaped section 2 and the cuboid box body are consistent with the theoretical height of the simulated shovel-type fault section, so that the disc rolling back-slope geometric form surface on the shovel-type normal fault can be accurately described in combination with the position of the fault surface of the shovel-type normal fault.

By combining the above embodiments, the teaching aid for demonstrating the principle of conservation of the upper plate layer length on the shovel-type fault to form the rolling anticline is specifically described. The embodiment of the utility model provides a teaching aid for demonstrating the principle of pan layer length conservation on a shovel type fault to form rolling anticline, which comprises a teaching aid base body 1, an arc-shaped section 2, a simulation plate 3, a sliding barrel 4, a sliding rod 5 and the like. Specifically, teaching aid pedestal 1 is transparent cuboid box for lay each required accessory. Arc section 2 and simulation board 3 set up the specific position department in the box, and arc section 2 is used for simulating shovel formula fault section, and simulation board 3 is used for simulating the hanging wall roll anticline aspect on the shovel formula fault. The sliding barrel 4 is arranged in the middle of the upper surface of the box body, the sliding rod 5 is in threaded connection with the sliding barrel 4, and the sliding rod 5 is rotated to drive the simulation plate 3 to bend and deform. The sliding barrel 4 is a transparent sliding barrel, and the sliding rod 5 is provided with scale marks so as to control the sliding distance of the sliding rod 5. A limiting groove 6 is further formed in the designated position on the arc-shaped section 2 and is clamped with a limiting protrusion 7 on the simulation plate 3 to fix the simulation plate 3 and prevent the simulation plate 3 from continuously moving downwards. It should be noted that the inclination angle of each sliding barrel 4, the distance between two adjacent sliding barrels 4, and the moving distance of each sliding rod 5 should all match with the theoretical model of the rolling anticline layer on the disk of the simulated shovel fault, so as to accurately simulate the rolling anticline geometry.

As shown in fig. 2, the calculation process of the inclination angle of each sliding barrel 4, the distance between two adjacent sliding barrels 4 and the moving distance of each sliding rod 5 is specifically as follows:
taking a point a 'on the arc, the point a' should be as close to one quarter of the circle as possible in order to better simulate the arc cross-section 2. And (3) making a perpendicular line from the point a ' to the datum line aL and intersecting the point b, measuring the length of ab, and taking a ' b ' on the arc as ab, namely, the arc length is equal to the length of the straight line segment. Wherein ab is a reference line segment. In order to obtain the length of the arc segment more accurately, a circle is used as a reference surface during design, so that the length of the arc segment can be calculated according to a central angle and a diameter. The arc length formula is as follows:
wherein l is the arc length, r is the radius of the circle, and pi is the circumference ratio; n is the central angle in degrees.
Then connect bb ', make the perpendicular line from b ' point to the datum line and intersect at point c, measure the length of bb ' and bc, pick b ' c ' on the circular arc as bc, wherein, bc is the reference line segment, draw out in turn like the above algorithm.
Moving down the connecting lines bb ', cc' and the like according to a parallelogram rule, connecting end to end, completing a fault track, and forming a device track.
The acute angle between the sliding barrel 4 and the vertical line, i.e. the inclination angle of the sliding barrel 4, can be calculated by using an inverse trigonometric function, for example:
the inclination angles of the other sliding barrels 4 can be obtained in such a way, and the error is small through measurement. Specifically, the inclination angle of each sliding barrel 4 is shown in table 1, the distance between two adjacent sliding barrels 4 is shown in table 2, and the moving distance of each sliding rod 5 is shown in table 3.
