の力と定義する。Next, a description will be given of a method of measuring the amount of deflection by the measuring machine having the above-described configuration. The amount of deflection is determined from the horizontal load and the vertical load of the main measurement wheel 4 measured by the two-component load meter 7 while the carriage 1 is traveling. Before the calculation of the amount of deflection, the arithmetic processing unit 9 divides the horizontal load data input by the vertical load to obtain a horizontal resistance value as a horizontal load per vertical load unit. Then, the deflection amount is calculated by multiplying the horizontal resistance value as a reference parameter by a conversion coefficient described later. In the present invention, the horizontal load is defined as a horizontal force required to move the main measurement wheel 4 forward, and the vertical load is defined as a vertical force acting on the main measurement wheel 4.

荷重を計測することとした。Here, the relationship between the amount of deflection and the horizontal load of the main measurement wheel 4 and the calculation of the horizontal resistance as a reference parameter for calculating the amount of deflection will be described. First, with respect to the former, the main measurement wheel 4 receives a vertical load from the heavyweight 6 and enters a state in which the main measurement wheel 4 enters the ground.
In order to move the main measurement wheel 4 out of the penetration, a force is required. In other words, it is noted that there is a correlation between the amount of ground deflection and the horizontal load of the main measurement wheel 4 such that the softer the ground and the deeper the penetration of the main measurement wheel 4, the more the horizontal force is required. However, in the present invention, in order to calculate the amount of deflection, the main measurement wheel 4 is set to a constant ground contact pressure, and the horizontal load of the main measurement wheel 4 traveling in this state is measured.

て水平抵抗値を求めることとしたのである。Next, the horizontal resistance value is used as a reference parameter for calculating the deflection amount because the horizontal load has a property of increasing in proportion to the vertical load, and the measuring vehicle 1
This is because when the vehicle is actually driven, the vertical load acting on the main measurement wheel 4 slightly fluctuates due to vibration or the like, so that it is not possible to calculate an accurate amount of deflection merely by measuring the horizontal load. In other words, even if the weight 6 is replaced in the present apparatus or the vertical load of the main measurement wheel 4 changes due to vibration during traveling, the horizontal resistance value is determined for the purpose of obtaining a uniform reference parameter. It was.

算出（Ｆ２）するものである。On the basis of the above relationship, a conversion coefficient for calculating the amount of deflection from the horizontal resistance value can be obtained by conducting experiments under various conditions using the above-described measuring device in advance. By storing the conversion coefficient in the arithmetic processing unit 9, the amount of deflection can be calculated based on data from the two-component load cell. Specifically, as shown in the flowchart of FIG.
The horizontal resistance T / P is obtained by dividing the input horizontal load T by the vertical load P (F1).
The deflection amount is calculated (F2) by multiplying by the above conversion coefficient.

The value differs depending on the measurement conditions such as the soil quality of the ground, the contact area of the measurement wheel, the vertical load, and the traveling speed of the measurement cart. However, it is also possible to obtain a conversion coefficient that can cope with all conditions by performing an experiment for obtaining sample data according to various measurement conditions.

The role of the displacement gauges 8 provided for 5b will be described. The displacement gauges 8... 8 are a main measurement wheel 4 and a sub measurement wheel 5a.
By measuring the amount of vertical displacement of 5b, it functions to acquire data for determining the shape, inclination, and the like of the ground surface at the measurement site. That is, since the amount of deflection of the ground by the two-component load cell 7 is measured in a very small range of several millimeters, when the site ground surface is inclined or has irregularities, it affects the measurement accuracy of the deflection amount. Sometimes. In order to solve this, in the present invention, the displacement meter 8 ...
8, the displacement of the main measuring wheel 4 and the sub-measuring wheels 5a and 5b during running is measured, and the measured displacement is input to the arithmetic processing unit 9 to determine the state of the ground surface. This is the basis for judging the validity of the numerical value of the horizontal resistance value T / P calculated based on this.

It is possible to determine the ground state before, during, and after the vertical load at the same point where the main measurement wheel 4 passes.
Specifically, the distance between the main measurement wheel 4 and the sub measurement wheels 5a and 5b is set to a length obtained by dividing the circumference of the main measurement wheel 4 into three equal parts. By acquiring the displacement data of the displacement gauges 8... 8 every / 3 rotation, before the vertical load at the same point,

In this embodiment, as shown in FIG. 4, the validity of the horizontal resistance value is separately determined (F5) even before the comparison with the ground surface state (F4) in order to ensure the measurement accuracy.

Therefore, it is not necessary to prepare a large dump or the like, which has been difficult to obtain conventionally, and it is possible to measure the amount of deflection in a narrow alley.
