胀缩土地基因地基含水量的增减而升降变形,建于其上的建(构)筑物也必然相应地作升降变形,当建筑物的挠曲变形超过容许挠曲变形值时,即开裂损坏,这是人们早已认识的规律。那么对建于胀缩土地基上的水池、水塔等水工构筑物和烟囱、烟道、锅炉等热工构筑物情况又是怎样?在设计、施工和养护工程中又应采取什么措施才能保证建(构)筑物不开裂损坏呢?下面就调查所得分述如下。一、水工构筑物水池和水塔都是用以储存水的池子和容器,若建于胀缩土地基上,其受力状态,应力分析,变形控制
Swelling and shrinking land foundation gene moisture content increases and decreases and rises and falls, and the building (structure) built on it will inevitably be lifted and deformed accordingly. When the building’s deflection exceeds the permissible deflection deformation value, it will be cracked. Damage, this is the law people have long known. What about the situation of hydraulic structures such as pools, water towers, etc. and thermal structures such as chimneys, flue pipes, boilers, etc., which were built on the basis of expansion and shrinkage of the soil? What measures should be taken in the design, construction, and maintenance projects? Structures and structures are not cracked and damaged? The following survey points are summarized below. First, the hydraulic structure tanks and water towers are used to store water in the pool and the container, if built on the expansion shrinkage ground, its stress state, stress analysis, deformation control
