Cabinet of Ministers Regulations No. 546 in Riga on 21 June 2004 (pr. No 38 12) amendments to the Cabinet of Ministers of 18 December 2001 No. 520 of the rules "rules for the Latvian et seq of the LBN 207-01" Ģeotehnik. Structures and bases "basic" Issued in accordance with article 2 of the law on construction of the fourth draw 1. Cabinet of Ministers of 18 December 2001, the provisions of the "rules on No 520 Latvian et seq of the LBN 207-01" Ģeotehnik.

Structure and base "". "; 1.2. The Latvian et seq of the LBN 207-01 "Ģeotehnik. Structure and base ": 1.2.1. Express 9 and paragraph 10 by the following:" 9. the basic and core design in the Latvian national standard requirements list by the recommendation of the Ministry of the economy limited liability company "Latvian standards" is published by the newspaper "journal". 10. If the basic structures and bases are designed according to EN EN 1990, EN EN 1991 and EN ENV 1997 standards, structures and ground meet the requirements set out in et seq. In Latvia, the parameters to be determined and the coefficient values shall be adopted in accordance with those standards. "; 1.2.2. put 58 as follows: "58. in determining ground deformation under this paragraph 56 et seq above calculation schemes, the average pressure p under the feet of the base must not exceed the base bottom calculated resistance R (kPa), which is determined using the following formula: R = γc1. γc2 [MγkzbγI + Mqd1γI ' + (Mq-1) dbγI ' + MccI]/k (7) and γc1, where γc2 – soil-building interaction between the base and the working conditions factor, which is determined using this annex 3 6 et seq.; k = 1, if the base of the soil strength characteristics of φ and (c) by direct examination; k = 1.1 if ground soil strength characteristics of φ and (c) determine in accordance with this annex 1 et seq; k-factor, which is 1 if the base width b < 10 m; kz = zo/b + 0.2, if the base width b > 10 m (here zo = 8 m);-low basic γI feet level of the soil in the weighted average specific weight (bottom, which is located below the groundwater level, it shall be determined, taking into account the lifting force of the water) (kN/m3), ' above the basic γI-foot level of the soil of average weighted specific weight (bottom, which is located below the groundwater level, it shall be determined, taking into account the lifting force of the water) (kN/m3), CII – associate (kPa) the bottom just below the base of the foot to the State; Mγ, Mq, Mc-factor, which is determined using this 5 et seq. table 1 of the annex or the following formula: = ψ Mγ/4 (8) Mq = 1 + ψ (9) Mc = ψ (ctgφI) ψ = π (10)/(ctgφI + π/2, φI) (10) ψ-dimensionless factor of transition; φI-bottom internal friction angle; D1-based incorporation depth (structures without basement) or reduced external and internal core into depth in metres (structures with basement), which is determined using the following formula: d1 = hs + hcfγcf/γI ' who (11) hs-bottom layer height over basic feet from the basement (m); hcf-basement floor design thickness (m); γcf-basement floor construction the weighted density calculation value (kN/m3); DB-distance (m) from gliding to the basement floor of the mark level if the basement width B 20 m. " 2. the rules shall enter into force by 1 September 2004.
