Consolidation test two common errors

Start void ratio is a constant e: ± A 1 ( Cool

pn. . Where a temperature of 4 ℃, the water density. The value of lg / cm. ... Shu 2, we can see from the soil mechanics, P. To the pressure P + pressure range 13T ●, ● a reduction coefficient of j (see Figure 2) Press (9), calculated a. One-tgn = el - ei + i by (9), we have Pi +:--( 9) (10) loop 3 compression modulus (see Figure 3) by (n) calculated a population of a DEst X10 (11 ) (11) and (2) the same as the current national standard for soil test method standard (GBJ12388) to calculate compression modulus of the public I4 ceremony will be (6) (7) (10) on behalf of the people (11) after finishing have a 1-LEs 』_ (12) ai ~ i +1 (12) style is the building foundation design (GBJ7-89) in the calculation formula for modulus of compressibility, can be seen (11) and (12) Calculate the compression modulus is the same, (12) in e for a given sample is fixed, while the compressibility ai-i + l for different pressure range is different, so the compression modulus Es at different pressure range is also changing. 3 compression modulus formula compare the above analysis, the national standard for soil test method standard (GBJ123-8 Cool

in the compression modulus of the formula (11) and the building foundation design (GBJ7-89) in the formula ( 12) is consistent with (12) and (1) to compare, as e. > E,, so by (12),[link widoczny dla zalogowanych], the calculated result is greater than (1-style results. This shows that (1) to calculate the compression modulus is conservative, the error is large,[link widoczny dla zalogowanych], the evaluation of the compressibility of soil and calculating the amount of ground deformation greater impact, so easy to cause objection. The following table projects the Beijing Golden Century of individual soil test compression modulus using Eq (1) and (12) Comparison of the calculated data sheet. Equation (1) type (12) Es values in Table 4 Comparison of conventional compression test data, the actual consolidation of Taiwan rational discrimination experiments are typical e-P curve should be shown in Figure 4. Figure A point corresponds to the pressure in the preconsolidation pressure is Pc, when the P Pc,[link widoczny dla zalogowanych], the soil is due to consolidation of state, pressure changes have a greater change in void ratio, compressibility of soil large modulus smaller. However, with] more than 4 Kids in the pressure range after the shift, the occurrence of a change in units of stress changes in pore smaller than Henan. that SUI smaller compression modulus and growing. That is,[link widoczny dla zalogowanych], when P> Pc, the use of (3) analysis to determine the reasonableness of results is right. If the PI Pc is a】 E s is the correct one. Thus, in analyzing the general reasonableness test data compression, you must contact the specific soil analysis of the stress history. 5 Conclusion From the above analysis, draw: text (1]) type and (12) is the current national standard in the formula, use them to calculate the soil compression modulus is the same. while (1) to calculate the compression modulus than that (n) type and (12) small, practical work must not be confused with the above concepts, we, following the calculation of the current national standard in the compressive modulus formula. To determine the correct analysis of test data compression units conventional reason, must contact the soil stress history specific analysis, which can not normally consolidated soil test data introduction of a law., capsule, ≮ '0 j jump to community Telecommunications dispatch center second floor reinforcement construction process to the Agency Xue Wei Yun-l1 level dispatch center of Posts and Telecommunications archives 4 Q, I5 fifth floor room, library, each room will be a Q wave, a total of seven asked the room asked the floor, the original design floor live load 1.5kN/mz, was replaced .0 kN / 'm. the floor load force increases, the need for floor reinforcement, reinforcement technology uses high-strength structural plastic to steel to concrete structure revolves Results on structural reinforcement to meet the requirements of a reinforced concrete floor, pull the design of the reinforcement in the building under design Southwest Architectural Design Institute to provide relevant data, the use of steel reinforced concrete structure, revolves around plastic construction technology and research centers of Liaoning adhesive concrete anchor technology engineering structures, based on normative standards: \CECS25: 90, building research centers of Liaoning \ More articles related to topics：
