Przewodnik krok po kroku do określenia zdolności do przenoszenia przy użyciu metody Terzaghi
Determining thee bearing capacity of soil is essential for designing safe foundations. Terzaghi 's methods provides a systematic approach to estimate the ultiming bearing capacity based on soil contributions and load conditions. This guidee outlines these steps involved in applicying Terzaghi' s methodd effectively.
Uzgodnienie z Terzaghi 's Bearing Capacity Formaa
Terzaghi 's formula calculates the ultimate bearing capacity (qu) of a shallow foundation as a combination of different soil failure mechanisms. The formula i s:
Xi1; Xi1; FLT: 0 Xi3; qu = cNc + qNq + 0.5γBNγ Xi1; Xi1; FLT: 1 Xi3; Xi3; Xi3;
Kiedy:
- Xi1; Xi1; FLT: 0 Xi3; Xi3; c Xi1; Xi1; FLT: 1 Xi3; Xi3; = cohesion of soil
- Xi1; Xi1; FLT: 0 Xi3; Xi3; q Xi1; Xi1; FLT: 1 Xi3; Xi3; = surcharge at foundation level
- Xi1; Xi1; FLT: 0 Xi3; Xi3; γ XI1; Xi1; FLT: 1 Xi3; Xi3; = unit wag of soil
- Xi1; Xi1; FLT: 0 Xi3; Xi3; B Xi1; Xi1; FLT: 1 Xi3; Xi3; = width of the foundation
- = = liczba próbek (w tym liczba próbek)
Etap-by- Stopień procesu kalkulacyjnego
Te procesy determinang soil parameters, kalkulating capacity factors, and appliying thee formula to find thee ultimate bearing capacity.
Step 1: Właściwości gleb glebowych
Obtain values for soil cohesion (c), internal friction angle (∞), unit wag (γ), ande surcharge (q). These are typically derived from soil tests.
Krok 2: Obliczanie Bearing Capacity Factors
Determine Nc, Nq, and Nγ using standard charts or formulas based on thee soil 's internal nal friction angle.
Step 3: Complute the Components
Oblicz each term of the formula:
Xi1; Xi1; FLT: 0 Xi3; Xi3; cNc Xi1; Xi1; FLT: 1 Xi3; Xi1; FLT: 2 Xi3; Xi3; QNq Xi1; Xi1; FLT: 3 XI3; Xi3;, And Xi1; Xi1; FLT: 4 Xi3; Xi3; 0.5γBNγ XI1; Xi1; FLT: 5 XI3; XIX3; FLT;
Step 4: Sum the Components
Dodać te trzy elementy, aby znaleźć te ultimate bearing capacity (qu).
