The article “Determination of geotechnical characteristic parameters<\/em>” follows the base principles of the Eurocode.<\/strong><\/p>\n

\u201cThe characteristic value of a geotechnical parameter shall be selected as a cautious estimate of the value affecting the occurrence of the limit state.\u201d
\n[EC7- 2.4.5.2 2(P)]<\/em><\/p>\n

Defining the geotechnical characteristic value<\/strong> means therefore to choose the geotechnical parameter that influences the behavior of the soil in that particular limit state and adopt a value, or an estimate, in favour of safety.<\/p>\n

If statistical methods are used, the characteristic value should be derived such that the calculated probability of a worse value governing the occurrence of the limit state under consideration is not greater than 5%.<\/p>\n

Assuming, for exmple, a characteristic value of 26\u00b0 for the soil friction angle with a 5% fractile<\/em>, means to hypothesize that there is a probability of five percent that the real value of the friction angle is less that 26\u00b0.<\/p><\/blockquote>\n

A cautios estimate of the geotechnical parameters is obtained through the following formula:<\/p>\n

\"1_cvsoil\"
\nwhere, for a normal distribuiton, for compensation of resistances (slope stability analysis, bearing capacity of shallow foundations<\/em>)<\/p>\n

\"2_cvsoil\"<\/p>\n

in absence of resistance compensation (plinths, bearing capacity of deep foundations<\/em>)<\/p>\n

\"3_cvsoil\"<\/p>\n

In the case of\u00a0resistances compensation<\/strong> the characteristic value of the geotechnical parameter is close to the mean value.\u00a0\u00a0<\/strong><\/p>\n

\"\"<\/p>\n

In\u00a0absence of resistances compensation<\/strong> the characteristic value is close to the minimum value.<\/p>\n

\"5_cvsoil\"<\/p>\n

PRACTICAL CASE<\/strong>
\nIt was performed a continous mechanic penetration test to a depth of 6.8 meters from ground level. The test was processed with the software Dynamic Probing<\/a>, obtaining the values for the angle of shearing resistance shown in the table below:<\/p>\n

\"\"<\/p><\/blockquote>\n

According to the indications reported in the literature, the angle of shearing resistance does not follow the normal statistical distribution, but its tangent xi=tan(fi), so we transform the angles in tangent:<\/p>\n

\"\"<\/p><\/blockquote>\n

Mean value m(xi)= 0,547799;
\nStandard deviation s(xi)=0,009417<\/p>\n

For compensated resistances
\n<\/strong>The value of the distributed parameter is calculated as:
\nxi=0,547799-1.645*0,009417\/root(34)=0.54518<\/strong>, with the transformation in angle, arctg(0,54518) we obtain 28.6\u00b0<\/strong><\/p>\n

For not compensated resistances
\n<\/strong>The characteristic value of the distributed parameter can be calculated as:
\nxi=0,547799-1.645*0,009417=0,532307, trasformed in angle arctg(0,532307)=28.0\u00b0
\n<\/strong><\/p>\n

In this case (large sample)<\/em> the difference between the obtained values is minimal, but the difference may become substantial for small samples (n<30)\u00a0<\/em>as in the majority of cases and for some geotechnical parameters, such as cohesion, which distributes its statistical value according to a logarithmic law.<\/p>\n

The software CVSOIL<\/a><\/strong> offers the possibility to analyze: numerous<\/span> samples<\/span>, dispersed<\/span> samples<\/span>, highly dispersed saples<\/span>, linear distribution<\/span>, tangent<\/span>, logarithmic <\/span><\/span>etc.
\nCVSOIL<\/a><\/strong> simplifies the user’s work allowing to automatically acquire the data to estimate from Excel, memory or directly from the software Static Probing<\/a> and\u00a0 Dynamic Probing<\/a>.<\/p>\n

In this short video you can see how data is beeing processed in\u00a0CVSOIL<\/a><\/strong><\/p>\n

\n

<\/p>\n

The estimation of the characteristic value of the geotechnical parameters is very variable especially when the samples are highly dispersed. CVSOIL<\/a> has the statistical models that follow the principles of the Eurocodes<\/a> and which allow to make an accurate estimate of the characteristic value of the analyzed parameter even in the case of very dispersed samples.<\/p>\n","protected":false},"excerpt":{"rendered":"
