[接上页] BUILDINGS ORDINANCE (Chapter 123) NOTICE The imposed load on this floor is not to exceed ........................................ kilograms per square metre. 建筑物条例 (第123章) 告示 此楼面之外加荷载每平方米不得超逾 ...............公斤 (L.N.98 of 1997) (2) Where floors of different rooms or different parts of floors have been designed for different distributed imposed loads, a notice in the form in subregulation (1) shall be suitably displayed in each room or on each part of the floor, as the case may be, indicating the variations. (3) For the purposes of this regulation the distributed imposed load designed in units of kPa shall be indicated in the notice in the form in subregulation (1) in units of kilograms per square metre by the conversion of 1 kPa to 102 kilograms per square metre. (Enacted 1990) Cap 123B reg 20 Site formation works PART IV SITE FORMATION WORKS (1) Site formation works shall be designed and constructed so that during construction and thereafter there is an adequate margin of safety of the works and the remainder of the site. (2) The carrying out of site formation works shall not render inadequate the margin of safety of, or cause damage to, any building, structure, land, street or services. (Enacted 1990) Cap 123B reg 21 Bulk excavation in area number 1 of the scheduled areas PART V BULK EXCAVATION (1) Bulk excavation in area number 1 of the scheduled areas shall not be carried out below levels determined by the Building Authority. (2) For the purposes of this regulation "bulk excavation" (大型挖掘工程) means all excavation except excavation for ground investigation, public utility trenches, drains, sewers or piles. (Enacted 1990) Cap 123B reg 22 Interpretation PART VI FOUNDATIONS In this Part- "ultimate bearing capacity" (极限承载力) in relation to ground that supports foundations, means the value of the loading intensity at which the resistance of the ground becomes fully mobilized or undergoes substantial deformation; "working load" (工作荷载) means the loads calculated in accordance with Part III which the foundation is designed to carry. (Enacted 1990) Cap 123B reg 23 Foundation works (1) Foundation works shall be carried out so as not to render inadequate the margin of safety of, or impair the stability of, or cause damage to any building, structure, land, street or services. (2) Where dewatering is to be undertaken, appropriate procedures shall be adopted and precautionary measures shall be provided to prevent any undue resultant deformation or other movement which could impair the stability of, or cause damage to, any building, structure, land, street or services. (Enacted 1990) Cap 123B reg 24 Site investigation Where foundations are to be constructed, a site investigation shall be undertaken to provide all the necessary information for the design and construction of the foundations. (Enacted 1990) Cap 123B reg 25 Allowable capacity for bearing, bond or friction of ground (1) The allowable capacity for bearing, bond or friction of the ground supporting any foundation under working load shall not exceed- (a) the ultimate capacity for bearing, bond or friction of that ground with an adequate factor of safety against failure; or (b) the value in relation to bearing, bond or friction of that ground such that the deformation or movement (including total settlement, differential settlement and lateral movement) will not be greater than that which can be tolerated by the building, building works, structure or street supported by the foundation,whichever is the less. (2) The ultimate capacity for bearing, bond or friction of the supporting ground shall be determined by- (a) suitable tests to establish the engineering properties of the supporting ground together with the application of recognized foundation engineering principles; or (b) testing of the foundation on site; or (c) other suitable methods.(3) Where the allowable bearing capacity is to be determined on the basis of the ultimate bearing capacity of the supporting ground, due consideration shall be given to all the circumstances, including the ground water conditions, the shape and depth of the foundation, the inclination and eccentricity of the loads, and the nature and slope of the surrounding ground, and, in the case of rock, the presence of dissolution features, the jointing of the rock and the spacing, dip, thickness and degree of weathering of the joints and any other relevant characteristics. (4) The allowable capacity of foundations for bearing, bond or friction resisting the combined effects of dead, imposed and wind loads may be increased by not more than 25% where such increase is solely due to wind loads. (Enacted 1990) Cap 123B reg 26 Pile foundations (1) All pile foundations shall be of adequate load carrying capacity and of recognized type suitable for the ground conditions. (2) The allowable load on pile foundations shall be determined by- |
