Thus, results from the three plate-load tests were readily comparable.

These samples were used in the laboratory for determination of unit weight, specific gravity, and particle-size distribution. Particle-size distributions of the gravelly cobble deposit and the sand matrix. Ret-Ser Engineering Agency assisted in setting up field load test equipment, and Mr.

The qu values of the 0.

A length of 12 m was used. However, the decreasing trend is not as sharp as those suggested by Terzaghi eqs.

These shear strength parameters along with a unit weight of Danish Geotechnical Institute, Bulletin Careful evaluation of the magnitude and variation of the KS value across a mat for a given project, using the bearing-capacity theories and the discrete-area method, is warranted in this regard.

The groundwater table was at a depth of about 5. Standard testing methods as prescribed in ASTM b were followed. Shoei-Muh Wei assisted in several aspects of this study.

For each plate-load test, a contact pressure of about Using a factor of safety of 1. This reinforces the observation about the relationship between the modulus of subgrade reaction and the size of the plate in the case of the gravelly cobble deposit. Before applying the loads, the pressure gauge and the dial gauge were set to zero. Aatm unified soil classification of the gravelly cobble deposit is GP.

In the first stage, where the load is less than kN tthe load is measured by a load gauge which has a maximum capacity of only kN t but is more accurate. The third layer, from 2 to 2.

Large Scale Plate Load Tests

It depends on several factors, such as the length and width of the foundation, the depth of embedment of the foundation, the type of structure, and the type of soil beneath the foundation. Since the voids within the gravelly cobble deposit at the test site are filled with sandy soils, the cohesion was assumed to be zero.

The length of the basin from north to south is about 48 km and the maximum width from east to west is about 14 km. Thus, while the plates were seated at different locations beneath the main reaction beam, the ASTM distance specification was not followed.

Wrench and Nowatzki also developed a relationship between the deformation modulus and N value. The apparent specific gravity r1194-94 the gravelly cobble deposit is 2. Exposure of gravelly cobble deposits from an excavation at the test site. Figure 1 shows a geologic map and profile of the Taichung Basin. Subgrade modeling for mat foundations: For a preliminary analysis, d1194-944 of KS values suggested by Terzaghi for different soils might be used as a basis to select an equivalent KS value.

Theoretically, if the contact pressure q and the settlement can be estimated, the modulus of subgrade reaction KS can be determined.

Sand- and siltsize particles fill the space not occupied by the gravel and v1194-94. Thus, it was concluded that the astn pull-out resistance of the eight reaction anchors would be 14 kN tmuch greater than the required total allowable load of kN t. The Tatu Terrace is mainly composed of Pleistocene sandstone and mudstone. The modulus KS decreases as the size of the plate increases. Effect of plate diameter and soil type on the modulus of subgrade reaction.

The individual reaction anchor was designed according to Littlejohn’s formula. Schematic diagram of the plate-load test setup: Settlement is caused by the contact pressure q.

The geologic formation of the gravelly cobble deposit 1d194-94 it very difficult to obtain large undisturbed samples for laboratory testing. Relationship between modulus of subgrade reaction and plate diameter.
